Mo2-L7c: What are the Cycles Happened in the Ecosystem?

Like energy, matter is not created or destroyed but is transferred through the environment.

Unlike energy, matter moves in cycles.

Sunlight Consumers
animals
eaten by death

Producers Decomposers
green plants death bacteria and fungi
water and
mineral salts decomposition
Dissipate Thermic
Soil
mineral salts + humus Energy

Let’s Begin Key Concept

What are the Cycles Happened in the
Water Cycles Ecosystem?
What form does water take in the water
Liquid water evaporates from oceans, rivers, and other cycle?
bodies of water.

The water vapor, which is a gas, rises into the
atmosphere, where it condenses and falls as
rain or snow.

Water moves across the surface of Earth in lakes,
streams, and rivers, soaks into the ground, or is taken
in by organisms, before eventually being released again,
continuing the cycle.
