consumer
This green pigment in chloroplasts captures light energy from the sun.
Chorophyll
Name the three female parts of a flower
Stigma, style, and ovary
This organelle is known as the 'powerhouse' because it releases energy from food.
Mitochondria
Male peacocks use colorful feathers to increase the ______ of finding a mate.
probability/likelihood
In a food web, these organisms break down dead matter and return nutrients to the soil.

What are the make parts of the flower?
Filament and anther
This thin, flexible outer layer controls what enters and leaves the cell.
The cell membrane
ome seeds have 'wings' or hooks; these structures help with seed ______.

This rule states that matter is not created or destroyed as it moves through an ecosystem.
Conservation of Matter
This process occurs in the mitochondria and releases energy by breaking down glucose.

flower
Unlike animal cells, plant cells have this rigid outer structure for support.
Cell Wall
This term describes the transfer of pollen from the male anther to the female stigma.
pollination
This type of diagram shows the complex, overlapping feeding relationships in an ecosystem.
