Chapter 45 and 46 Test

A biome with complex structure, warm weather, plentiful rainfall, and diverse species is a

A biome characterized by hot days, cold nights, and cacti is the

A forest found in a broad belt in northern Eurasia and North America, with conifers and swamps, is called the

A small marine amphipod has recently been discovered that carries a bad-tasting organism on its back, which is contrary to its normal behavior. If a fish ingests the pair, it immediately spits them back out. If the amphipod is alone, however, it is readily eaten. There is no apparent benefit or harm in this relationship for the “backpack” organism. This is probably a case of

A treeless region with little rainfall in the far north is the

A treeless region with little rainfall in the far north is the

All food chains begin with a photosynthetic producer.

All of the following are terrestrial biomes EXCEPT

All the populations of all the different species interacting with one another in the same environment is called

Among the many functions of wetlands is (are)
-providing food and habitats for fish, waterfowl, and wildlife.
-absorbing storm and overflow waters.
-purifying water by filtering it and breaking down toxic wastes and nutrients.

Approximately what percentage of the energy in one trophic level is incorporated into the next trophic level?

An ecosystem contains

As animals take in food energy approximately 10% of it is made available to the next level in the food chain. Which of the following is one of the ways in which the energy is used by the organism and not passed along?
-excretion
-cellular respiration
-death
-defecation

Clements proposed the climax-pattern model of succession. Governing factors for this model include
-climate.
-each successive community preparing the way for the next.
-soil conditions.

Climate is affected and/or characterized by all of the following factors EXCEPT

Compared with the numbers of grasshoppers or deer, there are not a lot of mountain lions. The reason that large and fierce top-level carnivores are rare in an ecosystem is that

Consider the consequences of a harmless prey that evolves toward mimicry of a model that has an antipredator defense (Batesian mimicry). What happens to the effectiveness of this defense as more and more prey in the population are harmless mimics? Then consider what happens when a species with bad taste evolves to resemble a model that stings (Mullerian mimicry).

Due to it’s high productivity and biological diversity this biome is considered the “nursery” of the sea.

Ecologist Robert MacArthur observed that five species of similar warblers coexisted on spruce trees because they

Energy flow in an ecosystem begins with

Energy flow in an ecosystem is not cyclic because energy is

Identify the correct sequence that freshwater will flow through.

Excluding humans, which group of organisms is most likely to change the abiotic factors within an ecosystem?
-detritivores
-producers
-herbivores

In a grazing food chain,

In an Asian rice paddy, carp eat decaying material from around the base of rice plants while a snail scrapes algae from the leaves, stems, and roots of the same plant. They can survive at the same time in the same rice paddy because they occupy

Is it possible that the carbon atoms in your body may have once made up the living tissues of another person or animal in earlier times? This is

MacArthur discovered that five species of warblers coexisted on spruce trees by foraging on the same caterpillar, but in different places of the tree canopy. This is

Major regional groups of interacting terrestrial ecosystems, characterized by climate and geography, are called

Primary succession takes much longer than secondary succession because it involves

Temperate deciduous forests are characterized by

The actual conditions under which an organism exists in nature constitute its

The largest biome on Earth is the

The only heterotrophs required in an ecosystem are

The relationship between plants and their pollinators is a good example of parasitism.

The sunlit portion of a lake is specifically referred to as the

The tropical grassland in Africa is called the

There are tubeworms and clams that live at the bottom of the ocean near thermal vents that do not have direct access to sunlight so they derive their energy from
