Bethel Biology Chapter 3

The tropical rainforest can be divided into layers of growth based on how much sunlight each layer receives.

Two different organisms living together and interacting so both benefit is known as commensalism.

A food web is composed of overlapping trophic levels.

A honey badger raids beehives for honey. This is an example of neutralism.

Which Biome? warm temperatures year-round; two seasons (wet and dry); wildebeests and lions

Which biome? warm, dry summers and cool, wet winters; diverse plant life; shrubs with tough, waxy leaves

Which of the following would be considered a biotic factor of an ecosystem?

All the organisms of the same species living in the same area are known as a(n)

Water temperature, dissolved oxygen, and gravel composition within a salmon stream are

On the big island of Hawaii, exotic mouflon live in herds. Collectively, they form an isolated

The layers within a biome due to elevation or depth of water are called vertical zonation.

The biosphere includes all the parts of the earth and its atmosphere where life exists.

Varying the types of plants growing in a garden or yard would increase its biodiversity.

No physical part of the earth's surface lies outside the realm of ecology.

Which Biome? oaks, birches, maples; raccoons, songbirds; four distinct seasons; moderate temperatures and rainfall

Temperature & precipitation are not affected by latitude or elevation.

Pelagic organisms are those that dwell on the ocean floor.

Symbiosis is when different animals live together and interact within a particular habitat.

The study of ecology includes the study of the interrelationships between organisms and

Dead plant and animal material is known as biomass.

Which biome? huge amounts of rainfall; year-round warm temperatures; sloths and poison-arrow frogs

Autotrophs are also known as

The term biodiversity refers to

When an organism depends on another organism for food, called the host, the dependent organism is exhibiting

Which of the following shows a plausible food chain?

A particular type of biome tends to be restricted to a small portion of the earth.

The smaller part of an ecosystem that an organism prefers to live in is known as that organism's

The average weather in an area over an extended period of time is the area's

Competition can occur between

The way that an organism lives in its habitat, including its effects on that habitat and other organisms, is its

The temperatures & precipitation amounts between adjacent climate zones tend to change abruptly.

A relationship in which one organism benefits but the other is neither helped nor harmed is

Regions of the biosphere that share certain environmental conditions and have a certain set of organisms are known as

Which Biome? hot or cold, but very dry; plants and animals conserve water and are often active at night

Which biome? moderate temperatures but not enough rainfall for trees; wild horses and pheasants

Two fish live in different areas of the river and eat different foods. This relationship is called amensalism.

Coyotes and bobcats both prey on small rodents. This is an example of

The total amount of living matter that an ecosystem can support is its

Which Biome? permanently frozen ground; little vegetation; caribou & grizzly bears

Which biome? hemlock, fir, redwood trees; cooler temperatures and moderate rainfall; elk, moose, wolverines
