Question

Describe how changes in an ecosystem can affect organisms that live there.

Answer 1

for example, if i cute down a forest, i am cutting off many animals, and their safety hide out (monkeys, birds ect) then they are on the floor or smaller trees letting their main predator is out to get them easier and causing their population to go down rapidly

Answer 2

Living things depend upon an ecosystem for food, air, and water, as
well as other things they need for survival. In turn, living things have
an impact on the ecosystem in which they live. Plants, as a biotic factor
in land ecosystems, affect other biotic and abiotic parts of ecosystems.
Plants are an important source of food. The types of plants found in a
particular ecosystem will determine the types of animals that can live
there. Plants can affect temperature by blocking sunlight. Plant roots
hold soil in place. Even the atmosphere is affected by plants taking in
carbon dioxide and releasing oxygen.

Answer 3

Animals, as biotic factors, also affect an ecosystem. A beaver that
builds a dam changes the flow of a river and so affects the surrounding
landscape. Large herds of cattle can overgraze a grassland ecosystem
and cause the soil to erode. In an ocean biome, corals form giant reefs
that provide food and shelter for marine organisms.

Answer 4

Abiotic factors include both the physical and chemical parts of an
ecosystem. Physical factors are factors that you can see or feel, such
as the temperature or the amount of water or sunlight. Important
chemical factors include the minerals and compounds found in the
soil and whether the ecosystem’s water is fresh or salty. It is the
combination of different abiotic factors that determines the types
of organisms that an ecosystem will support.
