What percent of sunlight does the grassland ecosystem receive?
Savannas receive an average annual rainfall of 30 to 40 inches. However in the temperate grasslands only about 20 to 35 inches. more info here: http://www.ucmp.berkeley.edu/exhibits/biomes/grasslands.php http://environment.nationalgeographic.com/environment/habitats/grassland-profile.html
What type of animal eats ducks?
A duck is a bird, which is a type of waterfowl. Puddle ducks are those that prefer smaller bodies of water such a shallow marshes and river. Diving ducks prefer deeper waters such as lakes and bays.
What are 3 rulesof species in biotic cummunity?
- Competition for resources: Different species within a biotic community compete for limited resources such as food, water, and shelter.
- Symbiosis: Species can interact in different ways such as mutualism, commensalism, or parasitism, where the relationship is either beneficial, neutral, or harmful to one or both species involved.
- Keystone species: Certain species within a community can have a disproportionate impact on the ecosystem, influencing the diversity and abundance of other species.
What part of the ecosystem do monkeys need to avoid?
Monkeys need to avoid predators such as big cats and birds of prey in the ecosystem to ensure their safety. They also need to be cautious of other territorial or aggressive animals that may pose a threat to them. Additionally, monkeys should avoid areas with limited food sources or where human activities may disrupt their natural behavior.
What role does tradition play?
Tradition often serves to preserve cultural values, practices, and narratives from generation to generation. It can provide a sense of continuity and identity for a community, fostering cohesion and connection among its members. Additionally, tradition can offer a framework for understanding the past and shaping the future.
The term mutualism is used to describe the relationship between two different organisms. This type of relationship is beneficial for both organisms and is sometimes referred to as co-operation.
What role do decmposers play in ecosystems?
Decomposers break down things so they can be reused in the ecosystem. For example, after a tree falls in the forest, bugs and other organisms start to break down the tree into nutrients that benefit the organisms and the other plants in the area.
What are good and bad points about natural levees?
Good: Natural levees provide some protection against flooding by acting as barriers that can contain the flow of water during high water levels. They can also provide fertile soil for agriculture due to sediments deposited during floods.
Bad: The presence of natural levees can sometimes give a false sense of security, leading to development in flood-prone areas behind the levees. If the levees are breached or overtopped, the flooding can be more severe and destructive due to the concentration of water flow.
How did polar bears get to Svalbard?
Polar bears likely arrived in Svalbard by drifting on sea ice from neighboring areas like Greenland or Russia. They are excellent swimmers and can cover long distances in search of food or new territory. The unique ecosystem of Svalbard provides suitable habitat for polar bears, hence they established a population on the islands.
What role does a saguaro cactus play in its ecosystem?
One way in which the saguaro cactus [Carnegiea gigantea] adapts to its desert ecosystem is by growing thick, columnlike stems. The stems are big enough to carry on much of the life sustaining activities for the entire plant. For example, the stems move, process and store nutrient solutions and energizing photosynthetic products. Concentrating all of these important activities in the place where they're most needed saves on energy.
Another way is by growing slow but tall. Its height casts a shadow on the soil around its base. This keeps available water - be it dew or rainfall - from evaporating. It allows the moisture to drip into the ground and be taken in by the cactus' roots. Additionally, the slow growth allows the plant to spread its energy use over a longer lifetime that may reach 150+ years.
Still another way is by growing shallow, fibrous roots. The roots spread out underground, to anchor the plant. They also hold together the soil, against erosion. And they seek out available water and dissolved nutrients.
Yet another way is by growing branches, flowers, and fruits late in life. A saguaro tends not to branch or flower until after it's 40+ years old. This is a wise, energy saving move. The cactus directs most of its energy to getting established in an extreme, harsh environment. Once accomplished, then it starts directing energizing photosynthetic products into reproduction.
go to youo090o0r local pet store and ask the manager for a bangaroo they ussually range beetween 20 and 30 dollars im glad to say i hellped you find your new bangaroo feed it tiwce a day and dont let it get soggy
The benefit of a food patch is primarily determined by the nutrition value and density of food in an area. A high density of food may encourage an animal to take greater risks whilst feeding. However, as an animal feeds, there is a critical point at which the density of food available no longer out ways the cost of feeding at that site. This is called the giving up density. When the giving up density of a food patch is reached, the animal will leave the site and forage somewhere else.
What concept refers to the number or different types or organisms that live in an area?
Biodiversity refers to the variety of different types of organisms that inhabit a specific area. It includes the diversity of species, genetic diversity within species, and diversity of ecosystems present in that area.
Is the population of a species diminishes abiotic or biotic?
The population of a species diminishes due to both abiotic and biotic factors. Abiotic factors like natural disasters, climate change, and habitat destruction can directly impact a population. Biotic factors, such as predation, competition for resources, and diseases, can also contribute to population declines.
What is a characteristics refers to a Savannah biome but not to a temperate prairie biome?
One characteristic that refers to a Savannah biome but not a temperate prairie biome is the presence of scattered trees, particularly Acacia trees in African savannahs. This is a distinguishing feature as temperate prairies typically have a more continuous grassland without scattered trees.
What is parasitism of a savanna?
Parasitism in a biome of such is quite similar to other biomes as well. It involves a parasite such as a tick or other bloodsucker in the ecosystem. This parasite could be feasting off of the animals like a African Elephant, lion, or characal in order to survive.
What are the physical factors that affect the living organisms?
Physical factors that affect living organisms include temperature, humidity, light intensity, soil quality, and air quality. These factors can impact an organism's growth, reproduction, and survival by influencing their metabolism, behavior, and overall health. Organisms have evolved to adapt to variations in these physical factors in their habitats.
What is pioneer and niche species?
Pioneer species are the first plants or organisms to inhabit a new or disturbed area, often able to colonize harsh environments. Niche species are organisms that have specific adaptations to thrive in a particular habitat or ecological niche, often playing a unique role in the ecosystem. Both types of species are important in ecosystem dynamics and succession.
The Miller-Urey experiment demonstrated that organic compounds, such as amino acids, which are the building blocks of life, could be produced from inorganic materials found in the early Earth's atmosphere. This experiment supported the idea that key components for life could have arisen from nonliving sources.
Do living things and nonliving things make up an ecosystem?
Yes, living things (biotic components) and nonliving things (abiotic components) together make up an ecosystem. Biotic components like plants, animals, and microorganisms interact with abiotic components like sunlight, water, temperature, and soil to create a balanced and interconnected system.
How do producers consumers decomposers interact with the abiotic factors in the ecosystem?
Producers interact with abiotic factors by utilizing them for photosynthesis, such as sunlight and nutrients in the soil. Consumers rely on producers for energy and nutrients, which are influenced by abiotic factors such as temperature and water availability. Decomposers break down dead organic matter and release nutrients back into the ecosystem, connecting biotic and abiotic components through nutrient cycling.
A community subsystem is a component within a larger community system that focuses on a specific aspect or function of the community, such as education, healthcare, or transportation. It operates within the broader community framework to address particular needs or facilitate services for residents. By understanding and working with community subsystems, organizations and policymakers can enhance their impact on specific issues within the community.
What is the most important role an organism plays in the ecosystem?
Every organism plays a vital role in the ecosystem, but some key roles include producers (like plants that make food), decomposers (like fungi that break down organic matter), and apex predators (like top predators that help regulate populations). Each of these roles contributes to the balance and functioning of the ecosystem as a whole.
Which occurs within a self-sustaining ecosystem?
In a self-sustaining ecosystem, energy is continually recycled through processes like photosynthesis and decomposition, ensuring that organisms have the resources they need to survive. Biodiversity also plays a key role in self-sustaining ecosystems, as a variety of species help maintain balance and resilience within the system. Additionally, nutrient cycling is an essential component, as nutrients are continuously taken up by plants, consumed by animals, and returned to the environment through decomposition.
