Biology Intro

Biology is important to learn because

• All living things rely on one another

• The Climate can be affected by our actions

• Knowing how things interact can limit pollution, climate change, and loss of species

• WE ALL PLAY A PART!

Why are producers important for ecosystems?

• They provide all the energy to the ecosystem

• They cannot easily be killed so they are a good food source

• They create habitats for consumers

• They are replaced quickly after being lost

What does it mean for an organism to be an invasive species?

• It harms the other organisms that live near it

• It moves in from another place and out competes with the native species

• It is brought from somewhere and benefits it's new ecosystem

• It grows quickly and can spread easily

Why should we be concerned about invasive species?

• They can take over a whole native ecosystem

• They usually are not useful to our economy (we can't make money off them)

• They are unattractive and do not match native habitats

• They are not edible by humans so we cannot eat them
