S2-U4L1- part 2

How are a plant's basic needs different from yours?

• A plant needs water, air, light, and nutrients to make its own food.

• We need to get our food from a store or grow it in a garden.

• People need shelter, like houses. Plants might give shelter to each other just by covering them up. 

Can a plant get too much of its basic needs? What happens then?

• A plant might get too much water and drown.

• A plant could get too much sun and burn. (Some plants grow best with lots of sunlight and some need only a little sunlight.)

• 
  

Multiple Select

Ocean plants cannot make their own food because there is not enough soil to get nutrients from. Is this true or false?

• True

• False

How do ocean plants get enough sunlight to grow?

• Most ocean plants live near the surface of the water, so light energy from the sun still reaches them. 

If plants use nutrients in the soil, why don't they use up all the soil?

• They only use a little bit of the nutrients, and when the plants die, they return to the soil and turn into nutrients as they rot.

• (Crops can sometimes use up all the nutrients in the soil, so plants will not grow there anymore. Farmers have to be careful this does not happen.)
