Moving through trophic levels _______. a. energy decreases b. entropy increases c. biomass decreases d. all of the above

Answers

Answer 1
Answer:

Answer: The correct answer is A) Energy decreases.

Trophic level is a hierarchical level within an ecosystem that comprises of organisms having same functions within a food chain and have same nutritional relationships with respect to the source of energy.

For instance, producers form the first trophic level and all producers synthesize their food through photosynthesis.

As per the 10% law of energy transfer, transfer of energy from one trophic level to the next ( like from producers to primary consumers) is 10% and the rest 90% of the energy is utilized in various metabolic processes and released as heat in the atmosphere.

Thus, energy decreases as we move through different trophic levels.

Answer 2
Answer: The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat. If a grassland ecosystem has 10,000 kilocalories (kcal) of energy concentrated in vegetation, only about 1,000 kcal will be transferred to primary consumers, and very little (only 10 kcal) will make it to the tertiary level. Energy pyramids such as this help to explain the trophic structure of an ecosystem: the number of consumer trophic levels that can be supported is dependent on the size and energy richness of the producer level.

B.
Osmosis is diffusion of water molecules across a membrane.

C.
Osmosis is diffusion in plants cells.

D.
Osmosis is diffusion in animal cells.

Answers

B, osmosis is the movement of water across a semi-permeable membrane according to the gradient of concentration. The water moves to were the concentration of  solute is higher, that way the solute concentration is equalized.

In which biome would you find organisms adapted to infrequent rain?desert
taiga
temperate forest
tropical rainforest

Answers

The biome where organisms are adapted to infrequent rain is the desert biome. This biome only covers approximately 1/5 of the Earth's surface. Most of these desert have soils which are rich in nutrients but have little organic matter. Only a few of large mammals survive in a desert since there is insufficient water and the temperature is high as well.

Answer:

desert biome.
