Answer: c. Lawn fertilizer that washes into neighborhood ponds likely causes algae to become more abundant.
Explanation:
Eutrophication is a natural phenomena in which the algal growth occurs in the water body due to increase in concentration of the fertilizers and manures being drained from the agricultural land into water. This causes decrease in oxygen level in water, and the aquatic animals in water will not survive due to scarcity of water.
According to the given situation, the growth of algae in the neighboring ponds is due to the drainage of lawn fertilizers into the neighboring ponds being washed from the lawns. This causes algae to grow abundantly in ponds.

Explanation:
Amphibians are the animals that spend their life partially in water and partially on land. They are cold blooded animals that cannot regulate their body temperature.
Some of the characteristic feature of amphibians are:
They have a moist skin but do not have scales on their body and gas exchange takes place through their skin.

Answer:
The polar bears which live in the tundra are not as omnivorous as the polar bears of the temperate forest because there are lesser plants and trees to be seen in the tundra region. The polar bears of the tundra are white in colour so that they can camouflage with the snow which is an adaptation for them to hide from their predators. The polar bears also have thick layers of fat which help to keep them warm as the temperature is very cold in these regions.
The choice of diet is important for organisms because an organism will be able to survive in an environment only if it has enough food sources to survive in a particular area. Hence, an organism should have the adaptation to feed on the sources of food available in an area in order to survive in the area.
