Why are fish important for the ecosystem?

To begin with, fish help the environment by eating spirogyra, duckweed and other aquatic plants from overgrowing (taking up all the space in thier territory). Some fish also clean an environment from dirt and mold. Plus they provide food for humans, bears, and other carnivores. People also keep them as pets. (As an opinion) some fish are even cool to observe. In conclusion, fish help the environment from many unexpected tragedies.

What are other factors that affect the NPP?

Other factors that can affect net primary productivity (NPP) include nutrient availability, temperature, water availability, sunlight, and disturbance events like fires or deforestation. Nutrient availability, such as nitrogen and phosphorus, is particularly important as they are essential for plant growth and productivity. Climate conditions also play a significant role, with warmer temperatures generally increasing NPP up to a certain point before diminishing returns set in.

"Intertidal" shallow water marine.

There are many more

Tropical

How is a climax community different than a primitive community?

A pioneer plant is one which will be the species first to inhabit a new, barren environment. (eg moss).

A climax plant is one which will dominate a mature fertile environment. (eg Oak trees).

What is paben role in the play?

Paben role in the play is he narrator(storyteller), social commentator and the light and hope of the entire play. They make the voice of the play that you are watching, or listening to. They narrate the whole storyline.

What is it called when all parts of an ecosystem are you Balance?

Homeostasis! Lets all strive to understand what an individual insect does or what an individual plant offers to the fauna and what insects and fauna offer to the plants. just know that if you have a small space, take time to think about what eats what. Take time to know what is causing the effect that you choose to change and what eliminating that part of the circle will do in turn to other parts. most things have there place in a sustainable environment or micro environment. Take time to study eace before you destroy. Just observe! Be close to it all and understanding will come.

What is macro ecosystem?

A macro ecosystem can be described as a single biological community of interacting living things and their physical environment that expands automatically into a set of communities. This term is form by the two words, macro and ecosystem.

What are principal characteristic that determines whether an aquatic ecosystem is classified as marine or freshwater?

The salinity level is the primary characteristic that distinguishes marine ecosystems from freshwater ecosystems. Marine ecosystems have high salinity, while freshwater ecosystems have low salinity. Additionally, the types of organisms and adaptations to salinity levels further differentiate these two types of ecosystems.

What does organic soil look like?

Organic soil is rich in color, usually dark brown or black. It has a crumbly texture and a earthy smell. Organic soil may also contain visible organic matter such as pieces of leaves or twigs.

Why would people use a density-independent limiting factor to control populations of introduced species?

People might use density-independent limiting factors, such as habitat modification or chemical control, to manage populations of introduced species because these methods can have a quick and direct impact on population size. They can help control invasive species that are causing harm to native ecosystems and species. Density-independent factors can be effective in reducing population levels without relying on natural predators or disease.

What would happen if the organisms that break down dead or decaying organisms were removed from an ecosystem?

The buildup of dead or decaying organisms would not be decomposed, leading to the accumulation of organic matter. This could result in nutrient imbalances, decreased soil fertility, and disrupted ecosystem processes. It could also potentially lead to the spread of diseases and parasites.

Which two finches could temporarily occupy the same niche?

Two finches that could temporarily occupy the same niche are the medium ground finch and small ground finch on the Galapagos Islands. During times of scarce food resources, these two species may compete for the same food sources, but their beak sizes and shapes allow them to specialize on slightly different seeds, reducing competition.

Is beeswax biotic?

Yes, beeswax is biotic. It is a natural substance produced by honeybees as they build their honeycomb structures.

Why are animals important to ecosystems?

In ecosystem ecology we put all organisms together and, insofar as we can, we try to understand how the system operates as a whole. This means that, rather than worrying mainly about particular species, we try to focus on major functional aspects of the system. These functional aspectsinclude such things as the amount of energy that is produced by photosynthesis, how energy or materials flow along the many steps in a food chain, or what controls the rate of decomposition of materials or the rate at which nutrients are recycled in the system.

Would periodic fires be a biotic factor for a chaparral biome?

Yes, periodic fires can be considered a biotic factor for a chaparral biome. These fires are often a natural part of the ecosystem, influencing plant diversity and promoting the growth of certain plant species with adaptations to fire. The plants and animals in the chaparral have evolved to withstand and even benefit from these fires.

What is the kingdom of lapu-lapu fish?

The kingdom of the Lapu-Lapu fish is Animalia, as they belong to the animal kingdom. They are further classified under the phylum Chordata, class Actinopterygii, order Perciformes, and family Lutjanidae. Lapu-Lapu fish are also known as snappers.

What forces can create new rock in primary succession?

In primary succession, new rock can be created through processes like volcanic activity, where lava solidifies and forms new rock, or through the deposition of sediments that eventually harden into rock over time. Additionally, the accumulation of organic material, such as plant debris or animal remains, can contribute to the formation of new rock through processes like lithification.

How do enviormental changes impact on ecosystems stability?

It effects it by once the producers die in that ecosystem, then the herbivores will starve to death and die then the carnivores will starve to death and die, so then there will be a big coroption in the food chain. The producers could die by having no water for along time or just getting dried out. == ==

How does energy flow from grassland to grassland?

Energy flows from grassland to grassland through the transfer of nutrients and energy between plants, herbivores, and carnivores. Solar energy is converted by plants through photosynthesis, which is then consumed by herbivores, and subsequently by carnivores. This energy transfer forms the basis of the grassland ecosystem.

How ecosystem can be conserved?

Ecosystems can be conserved through various methods such as protecting habitats, preventing pollution, practicing sustainable agriculture, and promoting biodiversity. Conservation efforts involve engaging local communities, implementing laws and regulations, and supporting initiatives that aim to preserve and restore ecosystems for future generations. It is essential to balance human activities with the needs of the environment to ensure the long-term health and sustainability of ecosystems.

What are several population of organisms living together in one area?

Several populations of different organisms living together in one area is called a community. Examples include a forest community consisting of trees, birds, insects, and other species, or a marine community with fish, plants, and coral. These populations interact with each other and with their physical environment in various ways.

How do decomposers during the primary succession process?

some are mushrooms, bacteria, or even some wild fungi

Are dandelions invasive species?

Yes, dandelions are considered invasive plants in many regions. They have a high reproductive rate and can displace native plant species, impacting biodiversity. Additionally, their ability to spread quickly and thrive in various conditions contributes to their invasive nature.
