How long does the Nitrogen cycle last?

The nitrogen cycle is ongoing and does not have a fixed duration. It is a continuous process in which nitrogen is converted between various forms by different microorganisms in the environment. The cycle involves steps such as nitrogen fixation, nitrification, assimilation, and denitrification, all of which occur at different rates and time frames depending on the environment and conditions.

How species diversity affect net primary productivity?

Greater species diversity can have a positive effect on net primary productivity as it enhances resource utilization and reduces competition for resources among species. Different species can fill different niches and maximize overall productivity in an ecosystem. However, too much diversity can also lead to decreased productivity if it disrupts established ecological relationships.

Are plastic bags from supermarkets recyclable?

because:

- made from crude oil

-non-renewable resources

- litter

- not biodegradable

- use energy to make

- when burned or biodegraded carbon dioxide is released

- to encourage customers to reuse bags / use their own bags.

What is Quick Horses Eat Orange Carrots in ecology on science?

Quick Horses Eat Orange Carrots is a mnemonic device used in ecology to remember the trophic levels in a food chain: Quaternary Consumers, Tertiary Consumers, Secondary Consumers, Primary Consumers, and Producers. This helps to understand the flow of energy in an ecosystem and how organisms at each level interact with each other.

What is a physical enviromental factors that influence life Ecology?

habitats are broadly classified as aquatic or terrestrial.in all these habitats many important physical factors are found interacting with other nonliving and living things these factors are: 1.soil-very important that lies in a thin layer on the surface of the bedrock of the earth.it is formed mostly from weathering of rocks and minerals and erosion by running water,wind and other forces of nature 2.temperature-tilting of the earth's axis contributes to the unequal distribution of temperature over the earth's surface.it may vary from region to region at given times bec. the rays of the sunstrike the earth at different angles. 3.water-it is found in every living cell 4. light-needed by terrestrial organisms 5.atmosphere-layer of gases surrounding the earth 6. topography-description of the physical features of the earth

Is cane sugar producer or consumer?

All plants: grasses, trees, brush or algae are producers because they producer their own food and they are green.

That is something we can't do, making all animals, slugs, worms, insects consumers since we need to eat food to live.

Sugar cane is a very large green grass.

Why is the butterfly bush considered invasive in southern states?

The butterfly bush is considered invasive in southern states because it can outcompete native plants for resources, leading to a decline in biodiversity. Its ability to produce abundant seeds and spread quickly through wind dispersal also contributes to its invasive behavior, especially in areas where it does not have natural predators to keep its population in check.

Why is sampling important for field ecology?

Sampling is important for field ecology because it shows the different effects that an area has on animals, plants, and people. Ecologists use sampling as a way of finding solutions to problems that may exist.

What are some of the ecological conditions that are necessary for human life to continue on Earth?

Living things obviously need water to survive they also need food to have energy. Air is another main thing, not all living organisms need oxygen though. Homeostasis. The ability to maintain homeostasis, equilibrium in the inner processes of an organism, is vital to the perpetuation of life.

What is the rafflesia arnoldii's method of seed dispersal?

The rafflesia arnoldii relies on carrion flies to pollinate its flowers. The plant emits a strong odor similar to that of rotting flesh, attracting the flies which then transfer pollen between flowers. Once fertilized, the plant produces large fruits containing seeds that are dispersed by animals that feed on the fruit.

Is rotting wood a living thing?

No. Rotting wood is part of a ex-living thing. The bacteria and/or fungi in it, that are causing the deterioration, are living things though.

How many years make 1 generations?

in one generation there are about a thousand years give or take 100 years

Answer:A generation s typically the time between a human births until that person has children. Grandfather to Father ti Son is three generations, Depending on cultural norms for being marrying age this is generally 20 to 30 years per generation


In astronomy the term generations can be used to escribe solar evolution. Our som is asecond or third generation star. As it is 4.5 billion years old and he Universe is some 14 billion years old, a generation for stars is arounf 4 to 10 billion years.


For bacteria the time between doubling is about 20 minutes giving them three generations per hour.

Why are belt transects useful?

Belt transects are useful in ecological studies because they provide a systematic way to sample and quantify the distribution of species within an area. By laying out a defined path and measuring the abundance of species along this path, researchers can gather valuable data on species composition, density, and diversity. This method is particularly helpful in studying the spatial distribution of organisms and understanding patterns in natural communities.

What is the use of funaria?

Funaria is a genus of moss that can be used in various ways. In nature, it helps with soil stabilization, water retention, and nutrient cycling. In the laboratory, Funaria species are also used in research and education to study plant biology and ecology.

Which organism receives the most energy on the pyramid of energy?

The energy pyramid is a way of gaining a conceptual understanding of energy flow in an ecosystem. There isn't really any animal at the top of the pyramid. Ultimately, the biggest animals die and are consumed by detritivores that would "normally" be placed at the bottom of the pyramid. So it's really a cycle.

Is milkweed drought tolerant?

Milkweed is not particularly drought-tolerant. It thrives in locations with consistent moisture and does not do well in long periods of drought. If grown in a dry environment, milkweed should be provided with regular watering to keep the soil moist.

Does ecological approaches have a valid place in contemporary criminological thinking?

Yes, ecological approaches have a valid place in contemporary criminological thinking. They emphasize the importance of understanding how social and physical environments contribute to criminal behavior, and how interventions can be targeted at these different levels to prevent crime. Ecological theories such as social disorganization theory and routine activities theory continue to be influential in explaining crime patterns.

What is the process of bringing a damaged habitat back to a healthy condition called?

The process of bringing a damaged habitat back to a healthy condition is called habitat restoration. This involves activities such as removing invasive species, planting native vegetation, and actively managing the habitat to support the recovery of its biodiversity and ecological functions.

Why is careful interaction among life forms important?

Careful interaction among life forms is important for maintaining ecosystem balance, promoting biodiversity, and supporting the overall health of the environment. It helps prevent negative impacts such as extinction of species, disruption of food chains, and loss of ecosystem services that are vital for human well-being. By fostering harmonious relationships between different organisms, we can ensure a sustainable future for all life forms on Earth.

What is the ecology role of liverworts and mosses to the terrestrial environment?

In the modern world the economic uses of mosses and liverworts are not immediately obvious. But they do have an important and subtle ecological role, both in water-retention and stabilising mobile surfaces like landslips, scree slopes and sand dunes. Examination of almost any handful of moss will also reveal another important ecological role - that of providing shelter and humidity for a remarkable diversity of invertebrates. This is an integral part of the food web in many of our important habitats.

How does biodiversity change with latitude and area?

Biodiversity generally decreases with increasing latitude, as the number of species tends to decline towards the poles. In contrast, biodiversity increases with larger areas as larger habitats can support more diverse ecosystems and species. This is due to the availability of more niches and resources in larger areas.

Where does the majority or rain water end up?

The majority of rainwater ends up flowing into rivers, lakes, and oceans. Some of it evaporates back into the atmosphere, while some is absorbed by the ground and vegetation. Ultimately, it plays a crucial role in the water cycle and replenishes sources of fresh water.

What is each level of a food chain or food web called?

In a food chain or food web, each level is called a trophic level. The first trophic level consists of primary producers, such as plants, that convert sunlight into energy through photosynthesis. The second trophic level comprises primary consumers, which are herbivores that feed on the primary producers. The third trophic level includes secondary consumers, which are carnivores that feed on the primary consumers.

What is the ecological pyrimad?

Ecological pyramids are graphical representations of the trophic structure and energy flow in an ecosystem. They consist of different levels representing different trophic levels (such as producers, herbivores, and carnivores) with energy transfer decreasing as one moves up the pyramid. They help visualize the relationships between organisms in an ecosystem and show the transfer of energy from one trophic level to the next.

What is the scientific name for when fungus spreads?

The scientific term for when fungus spreads is called fungal colonization. This refers to the process by which fungi establish and grow in a new area or substrate.
