Answer:

2

Explanation:

Erosion is when the soil that is on the top of the land gets washed away by moving water. Fertile soil can help in preventing erosion because there will be more plants on fertile soil. When something like grass or any plant grows, the roots will hold the soil together more firmly. Vegetation is an effective measure against land degradation.

RideAnS [48]

Answer:

Selective permeability is a property of a cell membrane that allows it to control which molecules can pass (moving into and out of the cell) through the pores of the membrane

Explanation:

The membrane is selectively permeable because substances do not cross it indiscriminately. Some molecules, such as hydrocarbons and oxygen can cross the membrane. Many large molecules (such as glucose, <u>Celluloso </u> and other sugars) cannot. Water can pass through between the lipids.

What does a pyramid of net production look like in a real ecosystem, and what are the trophic efficiencies? the pyramid below re
MatroZZZ [7]

Answer:

Idealized pyramid of net production uses the typical values of 1% for the conversion of sunlight energy to net primary production and 10% for trophic efficiency.

Explanation:

in real ecosystems, trophic efficiencies usually vary from about 5% to about 20%. As a result, net production diagrams for ecosystems have a pyramid shape. Two key factors explain why trophic efficiencies are relatively low, and thus why net production diagrams are shaped like pyramids. First, not all the organisms at one trophic level are eaten by organisms at the next trophic level. For example, not every plant is eaten by herbivores, and not every herbivore is eaten by carnivores. Second, because of the bioenergetics of animals, not all the food an animal eats is converted to new biomass.  Significant amounts of energy are lost in feces, used in cellular respiration, and lost to the environment as heat.
