Biology

salantis [7]3 years ago

Energy available to krill is 1500 calories

<u>Explanation:</u>

Energy produced by phytoplankton = 15,000 calories

Energy available to krill = ?

Along the food chain, only 10% of energy is transferred to the organism of higher trophic level.

Thus,

energy available to krill = \frac{10}{100} X 15,000

                                       = 1500 calories

Energy available to small fish = \frac{10}{100} X 15,00

                                                 = 150 calories

Energy available to medium fish = \frac{10}{100} X 150

                                                      = 15 calories

Energy available to large fish = \frac{10}{100} X 15

                                                 = 1.5 calories

mihalych1998 [28]

Carbon is most abundant in the <u>atmosphere</u> and <u>hydrosphere</u>.  

Explanation:

In the atmosphere, carbon is mostly present in the gaseous state of carbon dioxide. Plants absorb atmospheric carbon through photosynthesis and prepare food which is used by other living organisms. Respiration by plants and animals returns carbon back to atmosphere.

Next to atmosphere, carbon is abundant in the hydrosphere dissolved in water. Aquatic plants and marine organisms absorb carbon dissolved in water to prepare food. This carbon is also used to produce shells and other marine structures.

Carbon is also present in lithosphere and biosphere.

6. Which of the following is a product of photosynthesis?
sesenic [268]

Hello!

The answer to your question is B.

Oxygen.

Photosynthesis is a process which converts the energy in light into chemical energy in compounds. This process happens inside the living organisms which have chlorophylls. With the presence of sunlight and chlorophylls, organisms which can do photosynthesis produce glucose and oxygen as products by using carbon dioxide and water as materials.

Reaction is

6CO₂(g) + 6H₂O(l) → C₆H₁₂O₆(s) + 6O₂(g)
