A) a-ketoglutaric acid and NAD+
I think the answer is 42kg m/s.
Red foxes are omnivores. Their diet includes small animals such as birds, squirrels, rabbits and mice, but also berries, grasses and insects such as crickets, caterpillars, grasshoppers and beetles. Red foxes are therefore primary as well as secondary consumers, and even apex predators. Their removal from an ecosystem would most likely reduce the predation pressure on small animals and insects, and may result in population explosions of these prey animals. This in turn may result in additional pressure on the ecosystem as these animals exceed the carrying capacity, and could lead to other plant and animal species within the food web being decimated. Basically, the balance of the ecosystem would be lost until a new equilibrium can be established.
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.
