Jackson is doing an experiment to see how light effects the biomass growth of bean seeds. He places 6 ounces of soil/fertilizer in one pot, and repeats this procedure in an identical pot. He plants 7 grams of bean seeds in each pot. He finally waters the pots with 9 ounces of water each before placing one pot into a blackout box and the other under a greenhouse lamp. Identify the control variables in Jackson's experiment.
The control variables are: The amount of soil, seeds, and water.

C. Plants consume nutrients from the soil while humans make their own nutrients.
D. Plants cannot make their own nutrients while humans can.
A. Plants make their own nutrients while humans must consume nutrients.

In order to place an organism in the appropriate spot in a food web, you must know these two things, _______ & _________.
Predator and prey (What it eats and what eats them)
1.)An apple ripens and falls from an apple tree.
2.) A deer comes along and eats the apple.
3.) After digesting the nutrients from the apple, the deer "discards" the seeds from the apple as waste product, or feces.
4.) The seeds are then fertilized, and begin growing a new apple tree.
Which step from the scenario described above depicts the moment when biomass becomes "food" in the ecosystem's food web?
Step 2

B.) They could not grow and function.
On a farm ecosystem, a cow would be considered the primary consumer because _____________.
The cow eats the producer.
Johnny plant an apple seed next to his house in the yard. Which of the following best describes the niche of the seed?
A.) The seed's niche is a consumer because it will eventually be fertilized, grow, and provide food for consumers.
B.) The seed's niche is a decomposer because once it is a full grown apple tree, apples will fall from the tree and decompose leaving new seeds.
C.) The seed's niche is a producer because once the seed is fertilized, it has the potential to grow into a tree, providing food to primary consumers.
D.) The seed's niche is a population because it will produce more seeds that will grow into a forest of apple trees.
C.) The seed's niche is a producer because once the seed is fertilized, it has the potential to grow into a tree, providing food to primary consumers.
