How do plants get energy to grow?

Plants get energy to grow from the
sun.
How do animals get energy to
grow?

Animals get their energy to grow by
feeding on plants and/or other
animals.
What is the difference between a
producer and a consumer?

Producers can make their own
energy and consumers need to
search and eat theirs.
Name all the different types of
consumers, give an example of
each type, and explain how they
eat differently.

Herbivores-plants only-deer
Omnivores-both plants and animalsbear
Carnivores-animals only-tiger
Decomposers-break down dead
decaying organisms-mushroom
Scavengers-feed on dead organismsvulture
How do plants make food during
the process of photosynthesis?

Plants make food by trapping
sunlight and absorbing CO2 & water.
What part of the plant traps the
sun’s energy?

The part of the plant that traps the
sun’s energy is the chlorophyll in the
leaves.
What are the jobs of the roots?

The roots jobs are to take in water,
support the plant, absorb nitrogen
compounds, and store glucose (to be
used at night for energy).
Describe how Elodea and
Duckweed are different?


Elodea has leaves and a stem.
Duckweed grows in fronds and floats
on the surface.
What do Algae and Duckweed
have in common?

Algae and Duckweed both have no
leaves or stems.
Healthy Duckweed is what color?

Healthy Duckweed is bright yellow
green.
How does Duckweed grow and
reproduce?

Duckweed grows and reproduces by
having buds attached to the fronds.
What problems does Duckweed
cause when it thrives?

Duckweed can cause problems by
blocking out the sunlight on the
water’s surface.
What problems does Elodea cause
when it thrives?

Elodea can cause problems by
growing rapidly. This will clog
waterways and drainpipes.
What happens to Elodea if it breaks
apart?

Elodea will grow into 2 separate
plants if it is broken.
How does Elodea grow differently
in strong and poor light?

Elodea will lose it’s color and become
thin in poor light, but it will continue
to live.
What two ways can Elodea grow?

Elodea can grow planted or floating.
