Question

For example, ocean water at shallow depths may have less oxygen than open air, but there is still plenty of oxygen dissolved in the seawater. This makes shallow aquatic habitats an example of an ________ environment. Any organisms that survive here are likely able to use __________ to generate energy for the cell.

1. A. Arenerobic
B. Aerobic
2. A. Aerobic respiration
B. Fermentation

Many organisms, including multi celled organisms, can switch between aerobic and anaerobic forms of cellular respiration, depending on the conditions that surround the organism. However, _________ is by far the most efficient form of cellular respiration, so most of these organisms rely on it the majority of the time.
A. Aerobic respiration
B. Fermentation

Answer 1

The correct answer is option 2. A. Aerobic respiration.

Step-by-step explanation:

Shallow aquatic habitats, where there is less oxygen than open air but still a significant amount of oxygen dissolved in the water, are considered aerobic environments. Organisms that survive in these environments are likely able to use aerobic respiration to generate energy for the cell. Aerobic respiration is the process that most living things use to make ATP from glucose in the presence of oxygen. It is more efficient compared to its counterpart, anaerobic respiration, which also includes processes like fermentation.

Many organisms, including multicellular ones, can switch between aerobic and anaerobic forms of cellular respiration depending on whether oxygen is available. However, aerobic respiration is by far the most efficient form of cellular respiration, so organisms rely on it the majority of the time when oxygen is present. In contrast, fermentation provides an advantage by allowing organisms to live in places where there is little or no oxygen, making it crucial for survival in certain environments.
