Answer 3

Habitat

Question 4

Question 5

Living components of the environment

Answer 5

Biotic factors

Question 6

The variety of organisms in an area

Answer 6

Biodiversity

Question 7

The replacement of one kind of community by another at a single place over a period of time

Answer 7

Succession

Question 8

The development of a community in an area that has not previously supported life (bare rock, sand dune)

Answer 8

Primary succession

Question 9

The sequential replacement of species that follows the disruption of an existing community (farming, mining, forest fire)

Answer 9

Secondary succession

Question 10

Species that are typical of early successional stages. Small, fast growing, reproduce quickly

Answer 10

Pioneer species

Question 11

A large region characterized by a specific kind of climate and certain kinds of plants and animal communities

Answer 11

Biome

Question 12

The average weather conditions in an area over a long period of time. Two key factors are temperature and precipitation

Answer 12

Climate

Question 13

Receive large amounts of rain, warm all year, have the greatest biodiversity of any biome, home of half of earths species

Answer 13

Tropical rainforest

Question 14

Tropical grasslands, receive less rain than tropical rain forests, long dry seasons, shorter wet seasons, scattered trees and shrubs, typical of Eastern Africa

Answer 14

Savanna

Question 15

Moderate precipitation, cooler temps than savannas, found in the interior of continents, highly fertile soil

Answer 15

Temperate grasslands

Question 16

Grow in mild climates that receive plenty of rain, deciduous trees drop leaves in cold temps

Answer 16

Temperate forest

Question 17

Coniferous forests in cold, wet climates. Nutrient-poor soil, long cold winters. Moose, wolves, bears

Answer 17

Taiga

Question 18

Receives little rain, so plants are small, mostly treeless, shortest growing season, largest and northernmost biome, characterized by permafrost

Answer 18

Tundra

Question 19

Permanently frozen layer of soil under the surface

Answer 19

Permafrost

Question 20

Photosynthetic organisms that change light energy into energy they can use to grow

Answer 20

Producers

Question 21

The organisms that eat other organisms, cannot make their own nutrients

Answer 21

Consumers

Question 22

The organisms that break down dead and decaying matter

Answer 22

Decomposes

Question 23

Each step in the transfer of energy through an ecosystem. Each level contains about 90% less energy than the level below it

Answer 23

Trophic level

Question 24

A single pathway of feeding relationships among organisms in an ecosystem that results in energy transfer

Answer 24

Food chain

Question 25

Interconnecting food chains in an ecosystem

Answer 25

Food web

Question 26

Continuously moves water between the atmosphere, the land, and the ocean

Answer 26

Water cycle

Question 27

The continuos movement of carbon from the Nonliving environment into living things and back

Answer 27

Carbon cycle

Question 28

The process in which N circulates among the air, soil, water and organisms

Answer 28

Nitrogen cycle

Question 29

The movement of phosphorus in different chemical forms from the surroundings to organisms and then back to surroundings

Answer 29

Phosphorus cycle
