What effects does a high carbon level have on the deep ocean?
sergij07 [2.7K]

High carbon dioxide concentrations make it difficult for marine animals to breathe (to extract oxygen from seawater). This makes it more difficult for these animals to find food, avoid predators, and reproduce. Low oxygen concentrations can have similar effects.

<h3>What is the importance of oxygen for marine animals?</h3>

It is necessary for fish and other aquatic organisms to survive. Because of the aerating action of the wind, oxygen dissolves in surface water.

As a byproduct of aquatic plant photosynthesis, oxygen is also introduced into the water. Fish and other aquatic organisms cannot survive when dissolved oxygen levels fall too low.

High carbon dioxide concentrations make it difficult for marine animals to breathe (to extract oxygen from seawater).

This makes it more difficult for these animals to find food, avoid predators, and reproduce. Low oxygen concentrations can have similar effects.

Thus, these are the effect of high carbon level have the deep ocean.

according to the law of conservation of matter, matter is never created or destroyed. Yet in a food pyramid the amount of biomas
oksian1 [2.3K]

Answer:

According to the law of conservation of matter, matter is never created or destroyed but it can change from one form to another. Most of the biomass in a food web gets converted at each trophic level and it no longer remains apart of the food web. Most of the biomass is released into the atmosphere in the form of heat and hence cannot be transferred to the other trophic level. Also, matter is used up by the organism itself and converted into different forms. Most of the matter might get accumulated in the soil when the organisms of a trophic level die.

Irina-Kira [14]

Answer:

Pancreas.

Explanation:

Pancreas is an organ that acts as both exocrine as well as endocrine gland. As exocrine gland, it secretes digestive enzymes into the small intestine that help in digestion of complex food molecules.

As an endocrine gland, it secretes glucagon (from alpha cells) and insulin (from beta cells) hormones, directly into the bloodstream. Both of these hormones are responsible for the regulation of blood sugar level in the body.

Thus, the correct answer is 'pancreas.'
