13: Biogeographic Processes

Question 1

explores the distribution of plants and animals on the Earth

Answer 1

Biogeography

Question 2

studies the interaction between life

forms and their environments.

Answer 2

Ecology

Question 3

defined as a group of organisms and the environment with which
they interact

import and export matter and energy.

Answer 3

ecosystem

Question 4

refers to the flow of energy from one level to another in an
ecosystem.

Answer 4

food web,

or food chain,

Question 5

plants and animals that can create carbohydrates from

carbon dioxide and water and light energy through the process of photosynthesis.

Answer 5

Primary producers

Question 6

feed on the primary producers or on other consumers and transfer energy through different levels in this manner

Answer 6

consumers

Question 7

feed on decaying organic matter at all levels in the

food web

Answer 7

Decomposers

Question 8

absorbed initially by the primary producers and stored as chemical
energy which is digested by consumers

Answer 8

Solar energy

Question 9

Only __of the energy at
any level is passed on to the next level; consequently, the amount of organic
matter and consumers must decrease with each level

Answer 9

ten to fifty percent

Question 10

biochemical reaction which results in the production of carbohydrates and oxygen
using water, carbon dioxide, and light energy

Answer 10

Photosynthesis

H2O + CO2 + light energy = —CHOH— + O2

Question 11

process where carbohydrate is broken down and combined with oxygen
to create carbon dioxide, water, and chemical energy

Answer 11

respiration

—CHOH— + O2 = CO2 + H2O + chemical energy

Question 12

dependent on light and heat

increases with temperature to about 20°C and then levels off

Answer 12

Photosynthesis
