Question

what is ecosystem ?give an example.​

Answer 1

Answer:

An ecosystem is a community of living and non-living things that work together – it

consists of abiotic (soil, water, air) and biotic parts (flora, fauna). Ecosystems have no

particular size. An ecosystem can be as large as a desert or as small as a tree. The major

parts of an ecosystem are: water, water temperature, plants, animals, air, light and soil.

They all work together. If there isn't enough light or water or if the soil doesn't have the

right nutrients, the plants will die. If the plants die, animals that depend on them will

die. If the animals that depend on the plants die, any animals that depend on those

animals will die. All the parts in an ecosystem work together to achieve balance. A

healthy ecosystem has lots of species and is less likely to be damaged by human

interaction, natural disasters and climate changes. Every species has a niche in its

ecosystem that helps keep the system healthy.

1 Soil

Soil is a critical part of an ecosystem. It provides

important nutrients for the plants. It helps anchor the

plants to keep them in place. Soil absorbs and holds

water for plants and animals to use and provides a

home for lots of living organisms.

2 Air

The atmosphere provides oxygen and carbon dioxide

for the plants and animals in an ecosystem. The

atmosphere is also part of the water cycle. Without the

complex interactions and elements in the atmosphere,

there would be no life at all!

3 The sun

The heat and light from the sun are critical parts of an

ecosystem. The sun's heat helps water evaporate and

return to the atmosphere where it is cycled back into

water. The heat also keeps plants and animals warm.

The light from the sun is necessary for photosynthesis,

so that plants have the energy they need to make food.

4 Water

Without water there would be no life. Water is a large

percentage of the cells that make up all living

organisms. Water is also used by plants to carry and

distribute the nutrients they need to survive.
