When pollution enters through producers and accumulates at the apex predator this is known as _________.
Bioaccumulation

What is homeostasis, and why is it important?
The state of living or resting state for living organisms.
Why is an increase in carbon dioxide a concern for Earth’s climate?
More carbon in the air, higher temperature, less breathable oxygen for organisms.
If a plant produces 10,000 J of energy, how much energy will a mouse get from eating the plant?
1,000 J of energy
How does competition affect populations?
Competition causes populations to go down.

A person is sweating on a hot day. How does this help maintain homeostasis?
What is the chemical makeup of Water?
2 hydrogens, 1 oxygen.
Why is the population of apex predators usually the smallest at the top of the trophic pyramid.
High energy consumption, higher competition for limited resources.
True or false: Natural selection is an action a species can take to adapt to their surroundings.
False, Natural selection is the change in population due to environmental factors. Beaks of Darwin's Finches.
