Day and night

A forest is warm during the day and cool at night. A snake comes out at night. A rodent is active in the day.

Can both live in the same forest?

What this lesson covers

The idea

Different organisms living in the same habitat may use its resources in different ways and face different conditions, as night-active and day-active animals do, and so coexist in harmony.

Day and night

A forest is warm during the day and cool at night. A snake comes out at night. A rodent is active in the day.

Can both live in the same forest?

  • Yes, they face different conditions and coexist
  • No, they would fight all the time
  • No, only one can live there

Living in harmony

Each habitat has its own living and non-living components. Different organisms in the same habitat may use the resources in different ways and face different conditions. This is how living organisms coexist in harmony in the same habitat.

Different organisms in the same habitat may use its resources differently and face different conditions (for example, night-active and day-active animals). So they coexist in harmony.

Notes

Organisms in one habitat use resources differently, so they coexist in harmony.
