Exercise 1

Step 1

The term population is used for the group of individuals from the same species living in the same area.

“The total amount of matter decreases over time.” is not true.

Result

C. The total amount of matter decreases over time.

Step 1

1 of 4

In the biosphere, matter is always recycled since biogeochemical cycles are capable of transforming and reusing materials such as carbon, nitrogen, and phosphorus in various forms.

Step 2

2 of 4

Additionally, materials such as water and nutrients pass between organisms and the environment. The lack of nutrients can also lower the primary productivity of an ecosystem.

Step 3

3 of 4

Hence, the statement which is not true about the biosphere is that the *total amount of matter decreases over time*. In the biosphere, matter is always recycled and thus will not decrease.

Exercise 3

Step 1

1 of 2

The two ways in which autotrophs produce carbohydrates include photosynthesis and chemosynthesis. Therefore, sunlight and chemical energy are the sources of energy for living things.

Exercise 4

Step 1

1 of 2

Consumers are the organisms that rely on other organisms for food and energy. They are also called as heterotrophs. Heterotrophs include herbivores, carnivores, omnivores, detritivores, and decomposers.

E. I, II, and III

Step 1

1 of 4

The burning of fossil fuels releases carbon dioxide (CO$_2$) into the atmosphere. The process of photosynthesis captures CO$_2$ from the atmosphere, which is then converted into carbohydrates.

Step 2

2 of 4

Volcanoes can also release carbon dioxide gas into the atmosphere during eruptions. Lastly, the formation of fossil fuels stores excess carbon under the ground in the form of coal, oil, or gas.

Step 3

3 of 4

As we can see, **all** of these processes have something to do with various forms of carbon such as CO$_2$ gas. Therefore, **all** of these given processes participate in the carbon cycle.

As we can see in the given diagram, the pyramid of numbers shows the number of organisms in each trophic level. This includes the producers and various levels of consumers.

Step 2

2 of 3

In the pyramid of numbers, we can see that *the first-level consumers compose the greatest number of individuals*. This is shown by the large, blue rectangle that represents them.

Exercise 7

Solution 1

Solution 2

Step 1

1 of 2

The two pyramids resemble a forest ecosystem. It was evident in the biomass pyramid that there is a large amount of food available in the ecosystem. However, on the pyramid of numbers, it indicates that there are fewer producers than the first-level consumers. This means that there are only a few types of producers found in the ecosystem. In a forest, a single tree contains a large amount of energy and biomass. This explains why the producers are fewer in number in the pyramid of numbers, but there is a large amount of food in the biomass pyramid.
