3.2 Ecology Study Guide

Question 1

Tropic Levels

Answer 1

Producers
Primary consumers
Secondary consumers
Tertiary consumers

Question 2

Autotroph vs Heterotroph

Answer 2

Autotroph self feed. Where as, heterotrophs have to eat other animals to get energy.

Question 3

Herbivores

Answer 3

Herbivores are animals that eat plants.

Question 4

Question 5

Carnivores

Answer 5

Carnivores eat meat.

Question 6

Detritivores

Answer 6

Detritivores break down dead things from plants or animals.

Question 7

Forms of energy can take:

Answer 7

-light energy
-Kinetic energy
-potential energy
-heat energy
-sound energy
-sound energy
-vibration energy
-movement energy

Question 8

What is the rule of 10 and how does it apply to ecological pyramid models?

Answer 8

Trophic levels can only give 10 percent of it’s energy to the next level.

Question 9

Why is it considered more efficient to eat at a lower trophic level vs. a higher trophic level?

Answer 9

The lower tropic levels have more energy because there is not as much energy being lost through the transfer.
