Answer:
Algae produces food and catfish also needs warm water.
Explanation:
Sunlight regulates the productivity of algae and the number of catfish in a pool because algae produces food in the presence of sunlight during the process of photosynthesis. If algae produces more food, so more food is available for the catfish and as a result the population of catfish increases. If no sunlight occur on the pool the algae is unable to produce food and the population of catfish decreases. Sunlight increases the temperature of water which makes environment suitable for the catfish because catfish needs slightly warm water for its growth. So we can say that sunlight has a great affect on algae and catfish.
This is because the crowing of crops requires much less water and land than raising the energy equivalent in livestock. To explain, consider that most livestock are primary consumers, and are one level above primary producers, in this case, food crops. So there is a large loss in energy between primary producers and primary consumers. So if people chose instead to have a plant-based diet, satisfying their dietary needs could require much less water and land resources. Most livestock, particularly in developed countries, are grain fed. Therefore, grain is cultivated specifically for animal feed, and then people consume the animal protein after a large proportion of the original energy captured by the grain is lost.
