Green Generation Vocabulary

Question 1

Primary Succession

Answer 1

Succession that takes place in an area that has no existing soil (ex. after glacier recedes, volcanic explosion)

Question 2

Steady State

Answer 2

Final stage in logistic growth in which birth rate = death rate.

Question 3

Ecology

Answer 3

The study of the interactions of organisms with one another and with their environments.

Question 4

Specialists

Answer 4

Species with narrow niches (ex. anteater). Environments with lots of this type have high diversity.

Question 5

Logistic Growth

Answer 5

Growth typically experienced by populations.
Five stages:
1) slow initial growth
2) rapid exponential growth
3) population growth begins to slow
4) population slows even more still
5) Population reaches steady state in which growth rate is zero.

Question 6

Pyramid of Numbers

Answer 6

A food pyramid that illustrates the total number of organisms at each level.

Question 7

Answer 7

The amount of energy transferred from one trophic level to another.

Question 8

Commensalism

Answer 8

Type of symbiotic relationship in which one species benefits and the other is unaffected (ex. remora and shark)

Question 9

Question 10

Biosphere

Answer 10

The thin layer of air, land, and water on or near Earth’s surface in which all living things on Earth exist.

Question 11

Answer 11

Process that occurs at all trophic levels in which glucose and oxygen are broken down to produce carbon dioxide and water.
