Answer 20

Nodule.

Question 21

Answer 22

Pyramid of numbers.

Question 23

It feeds directly on a producer. What is it?

Answer 23

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

Question 24

What is latitudinal succession?

Answer 24

It is the continuous succession of community types from the equator to the poles.
It parallels altitudinal succession

Question 25

What do tropic levels in an ecosystem contain?

Answer 25

They contain specific types of organisms with a certain amount of energy available to them.

Question 26

What makes up the first tropic level?

Answer 26

Autotrophs, the producers

Question 27

Answer 27

Herbivores

Question 28

Higher up tropic levels are made up of what?

Answer 28

Second order and third order consumers.

Ex: The snake (2nd) that ate the mouse, and the owl (3rd) that ate the snake.

Question 29

It is a consumer of first order consumers.

Answer 29

Second order consumer

Ex. Snake < mouse

Question 30

What are decomposers?

Answer 30

Cause the decay of organic matter.

Question 31

In an ecosystem, organisms interact with one another and with the physical factors of their environment. True or false?

Answer 31

True

Question 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?

Answer 32

False, the sun is needed.

Question 33

Commensalism, parasitism, and mutualism are examples of abiotic relationships. True or false?

Answer 33

False, they are examples of biotic relationships because they are living.

Question 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?

Answer 34

False both are crucial factors.

Question 35

Variation in temperature influences the distribution of organisms and promotes many biological processes. True or false?

Answer 35

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.

Question 36

Life forms vary with altitude and latitude. Community types parallel one another in altitudinal and latitudinal succession. True or false?

Answer 36

True

Shows similar changes in community types.

Question 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?

Answer 37

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.

Question 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.

Answer 38

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.

Question 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.

Answer 39

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

Question 40

True or false: metabolic rate in animals is influenced by external temperature. When the temperature decreases the metabolic rate increase.

Answer 40

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.

Question 41

What happens to energy as you travel up the pyramid?

Answer 41

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

Question 42

What is nitrification?

Answer 42

The changes that involve ammonia reacting to water forming ions that become nitrate ions.
