. 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.

SCIENCEEEEEEEEE Frieda makes a pyramid of oranges for a display at the grocery store. A few minutes later, Corwin bumps into the display and the oranges spill down. Which change of state does the motion of the oranges most closely model?

Answers

The correct answer is A. Melting

Explanation:

Melting occurs in solids as these change their state to liquid state, usually due to high temperatures. For example, if one cube of ice is exposed to heat it melts. This physical change implies the solid loss its defined shape and particles in it are not as organized as before.

This process is exemplified by the situation of the oranges because the pyramid of oranges had a defined shape and the oranges were arranged in a defined pattern; however, in the end, this shape changes, and the particles (oranges) are no longer organized in a strict pattern. Also, the distance between particles increases, which also happens when solids become liquids.

Assuming you meant melts and not ments (if it was the latter, I have no idea what you mean), the answer is False. The melting point is when the substance melts, turning from a solid to a liquid. On the other hand, the boiling point is when the substance turns from a liquid to a gas.

Are flowers naturally rainbow colored? Please describe how the store can

Answers

Answer:

Answer in explanation

Explanation:

Capillary action: Inside the stem, there are tube-like transport tissue, called xylem, that brings water and nutrient to different parts of the plant. Water molecules are attracted to the surface of the xylem cells by weak electrical attractions. This sticky property is called adhesion. Water automatically moves up the xylem due to adhesion and the resulting movement is called capillary action​1​.

Cohesion: Water molecules are not only attracted to the surface of xylem (adhesion), but they are also attracted to one another. This property is called cohesion. Because of cohesion, water molecules fill the column in the xylem as they move up and act as a continuous stream of water​.

Transpiration: Water evaporates from the plant through transpiration. As water evaporates in the petals or any part of the plant exposed to air, a negative pressure is created in the xylem, resulting in suction pulling the water upward just like you draw water upward when you suck on a straw​.​
