Q

What does a food chain represent?

A

The passage of energy and materials through a community.

18
Q

What describes all the possible feeding relationships in an ecosystem?

A

A food web.

19
Q

What is altitudinal succession?

A

The continuous succession of community types from low to high altitudes.

20
Q

What is a swollen area on a root that contains nitrogen-fixing bacteria?

21
Q

What is a nitrogen fixation?

A

The plant process whereby nitrogen gas is changed to a usable form.

22
Q

The relationship showing the decrease in the number of organisms with each higher tropic level is the definition of terrible?

A

Pyramid of numbers.

23
Q

It feeds directly on a producer. What is it?

A

First order consumer. Ex: Cow grazing on grass. Deer browsing on foliage. Tadpole eating algae.

24
What is latitudinal succession?
It is the continuous succession of community types from the equator to the poles. It parallels altitudinal succession
25
What do tropic levels in an ecosystem contain?
They contain specific types of organisms with a certain amount of energy available to them.
26
What makes up the first tropic level?
Autotrophs, the producers
27
What makes up the second tropic level?
Herbivores
28
Higher up tropic levels are made up of what?
Second order and third order consumers. | Ex: The snake (2nd) that ate the mouse, and the owl (3rd) that ate the snake.
29
It is a consumer of first order consumers.
Second order consumer | Ex. Snake < mouse
30
What are decomposers?
Cause the decay of organic matter.
31
In an ecosystem, organisms interact with one another and with the physical factors of their environment. True or false?
True
32
Since energy is transferred through the tropic levels of an ecosystem by food chains, the sun is not needed to maintain and ecosystem. True or false?
False, the sun is needed.
33
Commensalism, parasitism, and mutualism are examples of abiotic relationships. True or false?
False, they are examples of biotic relationships because they are living.
34
The amount of rainfall and not sunlight is the crucial factor in the determination of dominant plant life in a given area. True or false?
False both are crucial factors.
35
Variation in temperature influences the distribution of organisms and promotes many biological processes. True or false?
True Ex. Peach trees bloom when it is warm, but they must first be exposed to chilling during the winters. The trees will not bloom without the chilling.
36
Life forms vary with altitude and latitude. Community types parallel one another in altitudinal and latitudinal succession. True or false?
True | Shows similar changes in community types.
37
Temperature affects life in water more than it affects life on land. There is less variation in temperature on land than in the ocean. True or false?
False, because on land we will have 20 degrees temperature changes from day to night in the summer. But in the ocean it doesn't change 7 degrees in a whole year. If this was seen it would be catastrophic.
38
True or false: processes such as respiration and photosynthesis and the activities of decomposers and scavengers recycle materials such as carbon, hydrogen, and oxygen in an ecosystem.
True: they contribute to the continuous carbon cycle. For example: the byproducts of photosynthesis are energy and oxygen that is releases into the atmosphere but they take in carbon, creating a cycle.
39
True or False: the nature of the soil doesn't determine the type of plants that can live there, which in turn determines the variety of animals that will in habit the area.
False: the type of soil does determine the plant life that in turn determines that animals that live there. For Example: if the soil is very fertile (rich in nutrients) then it is a good farming environment which encourages herbivores (like deer) and carnivores (like wolves) to live in that area
40
True or false: metabolic rate in animals is influenced by external temperature. When the temperature decreases the metabolic rate increase.
False: the metabolic rate and temperature are increased and decreased in result of each other therefore when temperature increases, metabolic rate increases, vice versa Example: in the winter, metabolic rate decreases due to cold temperatures.
41
What happens to energy as you travel up the pyramid?
The energy that's available to each next level is lesser than the one before it. Example: producers have more energy available to them (sun) than first order consumers who eat the producers due to loss of energy from life functions and lost as heat
42
What is nitrification?
The changes that involve ammonia reacting to water forming ions that become nitrate ions.
