How much chemical energy (stored as biomass) is available to primary consumers from 10,000 kcal of primary productivity?

Biology
1 answer:
atroni [7]2 years ago
7 0
The answer is “d” (1,000 kcal). As the trophic level increases energy is decreases by 10 times that of the previous level. If a system has 10,000 kcal, then the primary consumer have 10 times less (10,000/10) which is 1,000 kcal. The secondary consumers have 100 kcal and the tertiary have 10 kcal. Only 10% of the energy at each trophic level goes on to the next.

Which statement describes littoral zones?
Dima020 [189]
The best answer is E) All of the above. 

The littoral zone is the region where the land meets a body of water, and although the exact definition can vary, it generally includes land that is always dry and a region that is always submerged. A and B more or less say the same thing, and both describe the littoral zone. It almost always features vegetation (think of plants growing out of marshes and near/in the shore of rivers and lakes). It stabilizes the soil by providing a more gradual transition from land to water. For example, an area that only the high tide of the sea reaches will feature some chemical composition of the sea bed, such as more water and salinity, and some of the land further inland.
