. Distinguish between gross primary productivity and net primary productivity. Explain how net primary productivity affects the number of consumers in an ecosystem and on the earth. List two of the most productive ecosystems or aquatic life zones and two of the least productive ecosystems or aquatic life zones. Use the concept of net primary productivity to explain why harvesting plants from estuaries, clearing tropical forests to grow crops, and harvesting the primary producers in oceans to feed the human population are not good ideas.

Answers

Answer 1

Answer and Explanation:

The gross primary productivity corresponds to the sum of all the energy produced by the plants (primary producers) during the photosynthesis process. The net primary productivity, corresponds to the gross primary productivity value, even the energy value used by the plants in the metabolic processes that they present, in this way, we can conclude that the net primary productivity is the energy that is available for the living beings that consume the vegetias.

The ecosystems with the highest level of productivity are those that have a large number of vegetables with full access to the sun, in this case, we can mention forests and ecological parks. On the other hand, ecosystems with lower levels of productivity are those with a low number of plants, such as cities and areas with deforestation.

Because of our need to consume energy from net primary productivity, we are constantly harvesting vegetables and some photosynthetic water products to use in our food. However, this causes us to remove vegetables from nature and decrease the amount of gross primary productivity that ecosystems would have, and, consequently, decreasing the amount of net primary productivity that we need so much.

Which of the following best explains why matter must travel through cycles?
a
There is an unlimited amount of matter in the universe, so it can take on any form at
any time.
b
There is a fixed amount of matter in the universe, so it must take on different forms
at different times.

Answers

The answer is A hopefully this helped

Elements flows within ecosystem in various ways. It is important for matter to travel through cycle as there is a fixed amount of matter in the universe, so needed to be recycled.

What is cycling of matter?

Matter cycling is movement of matter from one form to another or from one place to another on the Earth, inside its ecosystems.

Matter is constantly cycling from place to place, and this can have both positive or negative effects. Matter also cycles naturally, or can be due to human activity.

As there are only finite number of nutrients on the Earth, so, it is necessary for them to be recycled in order to ensure the continued existence of living organisms.

Thus, option b is correct.

5 Devise Imagine that one tree outside your
school looks unhealthy, although all the other
trees seem healthy and strong. Describe how
you could apply scientific thinking to the
situation.

Answers

The first step is to identify the problem. There are factors to consider in keeping a plant or a tree healthy. These include water, oxygen, sunlight, soil, nutrients, climate, and other environmental conditions. If the environment seems to suit the other trees in the garden, ruling out other factors can be useful in determining why only one tree seems to be unhealthy. Once the problem is identified, a scientific investigation must be done to gather data and pieces of evidence which can explain why this event actually occurred. One of the best ways to gather evidence is through observing the tree and checking other signs which might identify if the tree is diseased. Once the gathered data are analyzed and the cause is identified, proceed in thinking of ways on how to solve it. In seeking a solution, it is best to ask information from experts and proper authorities.

I included an example of something both living and biotic, such as flowers.

I included an example of something biotic, but not living, such as paper.

I used compare-and-contrast vocabulary.

Explanation:

As you all know that living is a synonym for biotic, as both discuss the measures of life. It significantly includes plants, animals, humans, predators, etc.

What is biotic?

Biotic may be defined as something that is closely related to living organisms or something that is directly derived through the action of living organisms.

As compared to living, biotics may not always be alive, but it talks for a long period. Biotic is something that has once lived or emanated from something living.

Examples like plants, animals including humans are categorized under the category of living, while products such as rubber, latex, cow dung, paper, etc are biotic products that are not living.

Therefore, as you all know that living is a synonym for biotic, as both discuss the measures of life. It significantly includes plants, animals, humans, predators, etc.
