How can an ecosystem support a variety of organisms?
The number of organisms an ecosystem can support depends on the resources available and abiotic factors, such as quantity of light and water, range of temperatures, and soil composition. Given adequate biotic and abiotic resources and no disease or predators, populations (including humans) increase at rapid rates.
What is the variety of organisms in an ecosystem?
Biodiversity refers to the variety of living organisms within a given area.
In which ecosystems can the greatest variety of organisms be found?
Species richness is greatest in tropical ecosystems. Tropical rain forests on land and coral reefs in marine systems are among the most biologically diverse ecosystems on Earth and have become the focus of popular attention.
Which best explains why many kinds of plants and animals can live together in an ecosystem?
Which best explains why many kinds of plants and animals can live together in an ecosystem? The plants and animals are all part of a food chain and depend on each other to live.
What needs an ecosystem support?
Providing living spaces for plants or animals and maintaining a diversity of plants and animals, are ‘supporting services’ and the basis of all ecosystems and their services. Agriculture, forestry and fisheries are influenced and influence all types of ecosystem services.
How many organisms can an ecosystem support?
The number of organisms that an environment can support (its maximum population) is called its carrying capacity.
Why organism is important in maintaining the stability of ecosystem?
Living organisms change soil composition, chemical features, the composition of the atmosphere as well as the hydrosphere, oxygen-carbohydrate balance and, fmally, the structure and functions of the biosphere. They create the conditions necessary for life and ensure biosphere stability.
Why are different organisms needed in an ecosystem?
Animals in an ecosystem compete for food, mates and their territory. Organisms which have more of these resources tend to grow more healthily and are more likely to have offspring.
What are three reasons that organisms interact?
What are three reasons that organisms interact? Organisms interact because of mating, competition for food resources, defense, and assertion of dominance.
Which best describes a forest ecosystem?
A forest ecosystem describes the community of plants, animals, microbes and all other organisms in interaction with the chemical and physical features of their environment: Specifically, a terrestrial environment dominated by trees growing in a closed canopy — a forest, in other words.
Which statement best compares forest ecosystems to grassland ecosystems?
Which statement best compares forest ecosystems to grassland ecosystems? Forest ecosystems have higher average temperatures than grassland ecosystems. Forest ecosystems receive more precipitation than grassland ecosystems. Grassland ecosystems receive more precipitation than forest ecosystems.
Which of these ecosystems supports the widest variety of plants and animals?
Tropical rainforests support the greatest diversity of living organisms on Earth. Although they cover less than 2 percent of Earth’s surface, rainforests house more than 50 percent of all plants and animals found on land.
