Question

Marked temperature changes in the aquatic environment can affect

• A. breeding of animals
• B. more growth of aquatic plants.
• C. process of digestion in animals
• D. availability of nutrients

Answer 1

The correct option is A

breeding of animals

The correct option is A

Explanation for the correct option:

1. Earth is covered 71 percent with water. Most aquatic animals are cold-blooded organisms.
2. That means they survive and grow at lower temperatures. Warmer waters make them susceptible to parasites and diseases.
3. Higher temperature reduces oxygen levels in the water, further reducing its availability for respiration.
4. High environmental temperatures can cause a decrease in fertility, semen quality, and sperm production.

Explanation for incorrect options:

Option B

1. The growth of aquatic plants depends on temperature only to a certain limit.
2. If the temperatures are too high it may deteriorate the growth, and they may die

Option C

1. The process of digestion depends on the inner heat in the body and not the outer temperatures.
2. Young animals generate more heat due to higher metabolism and a faster digestion process.

Option D

1. Nutrients in water are either in form of dissolved minerals or present in the ocean bed soil.
2. The temperature has a negligible effect on nutrient availability.

Final answer: Marked temperature changes in the aquatic environment can affect the breeding of animals
