Answer:
The percentage of this energy is 96 available to consumers and decomposers.
Explanation:
Step : 1 The act of respiration allows the wildebeest to access the food's remaining energy. The source of energy in an ecosystem is. Creatures either consume (eat) plants directly or consume other animals that have consumed plants to obtain their food and subsequently their energy.
Step : 2 Animals that seek or kill other creatures for food are known as predators, while the victim is referred to as prey. So the predator that hunts wild animals for food is the animals.
Carnivores and omnivores, who feed on herbivorous primary consumers, are considered secondary consumers. The lion is a secondary consumer as a result. Wild animals are the main consumers since they devour vegetation.
Step : 3 The flow of energy is represented by the food chain. Due to the fact that producers are autotrophs, energy flow begins there. The creatures that can make their own nourishment are called autotrophs. In the case above, the producers are the plants that the wild animal is eating.
Step : 4 The major consumer is thought to be a wild animal that eats vegetation. Typically, herbivorous animals are the main consumers. Due to their heterotrophic nature, they are unable to manufacture their own nourishment.
The animals will now be discussed. The wild animal is consumed by the animals, who is regarded as its secondary consumer.
