"The Meaning of Biodiversity" Biological Diversity PPT Courseware 4

Biodiversity and us

What do we do in a day? How many of them are biologically related?

Plants are closely related to our lives

Human life cannot be separated from plants

1. Provide food for humans;

2. For human appreciation;

Biodiversity and other organisms

Just as human life cannot be separated from biological diversity, every living thing also needs to live in a biologically diverse environment.

Flowers need insects to help with pollination

Can we give other examples?

Sea anemones can provide shelter for clownfish, and clownfish swimming can bring food to sea anemones.

Soybeans and rhizobia are mutually beneficial, and rhizobia can fix nitrogen for soybeans

We could give many more such examples.

1. Ants and worms live in symbiosis. The intestines of ants provide an oxygen-free environment for the worms, and the worms can nitrocellulose.

2. Sea anemones can provide shelter for clownfish, and clownfish swimming can bring food to sea anemones.

3. Orchids in tropical rainforests rely on tall trees to grow without falling.

4. Soybeans and rhizobia are mutually beneficial, and rhizobia can fix nitrogen for soybeans.

5. Lynx feeds on snowshoe hare

6. Roundworms require the human intestine as a parasitic environment to survive

7. All viruses are parasitic and must live in living cells.

8. Paramecium must feed on other small plankton to survive

9. Big fish eat small fish, small fish eat shrimps

10. The rhinoceros provides small bugs as food for the birds, and the birds deworm the rhino.
