why is anaerobic respiration useful?​

Answers

Answer:

It is useful during exercise. When the body doesn't get enough oxygen during exercise, it relies on anaerobic respiration for an energy supply. Instead of carbon dioxide and water, however, anaerobic respiration produces lactic acid. Also, anaerobic respiration releases less energy than aerobic respiration but it does this more quickly.

give one disadvantage of having a large number of stomata per mm squared of leaf surface

Answers

Answer:

The downside to wide open stomata is increased water loss (transpiration). So stomata of cool-season turfgrasses have decisions to make. The plant needs to capture and store energy via photosynthesis, however, excessive water loss through transpiration can result in plant injury or death.

One disadvantage of having a large number of stomata per mm squared of leaf surface might be the excessive loss of water.

What are stomata?

Stomata are specialized plant structures used to exchange gases such as oxygen and carbon dioxide.

The plant structures (stomata) are especially located on the leaves where photosynthesis mainly occurs.

In conclusion, one disadvantage of having a large number of stomata per mm squared of leaf surface might be the excessive loss of water.

Sources of energy and the two processes for land autotrophs (producers) and autotrophs in the deep ocean.

Answers

Autotrophs on land get their energy indirectly from the sun while those in the deep ocean get theirs from chemicals.

Photosynthesis and Chemosynthesis

Autotrophs on land get their energy from carbohydrates synthesized via photosynthesis.

Photosynthesis is a process that converts radiant energy from the sun to chemical energy locked in carbohydrates. These carbohydrates are then broken down during respiration in order to release the locked energy.

Autotrophs in the deep ocean lack access to sunlight and thus, cannot utilize radiant energy from the sun. Instead, they make their carbohydrates by making use of energy from chemicals like hydrogen sulfide and methane in a process called chemosynthesis.
