OBJECTIVE FORESTRY

Detailed explanation-1: -Carnivores (organisms that eat meat) and omnivores (organisms that eat plants and meat) occupy the third level. Both primary (herbivores) and secondary (carnivores and omnivores) consumers are heterotrophs, while primary producers are autotrophs. A third type of heterotrophic consumer is a detritivore .

Detailed explanation-2: -Omnivores are animals that eat both plants (autotrophs) and animals (heterotrophs). Autotrophs are organisms that have the ability to undergo photosynthesis in order to make their own food. Plants and algae are autotrophs, also known as producers, and they make food in the form of the sugar glucose.

Detailed explanation-3: -Bacteria, fungi, yeast, cows, dogs, humans are all heterotrophs. They all depend on plants and other animals for their food.

Detailed explanation-4: -Carnivores eat the meat of other animals. Herbivores eat plants. Omnivores can eat both meat and plants. Scavengers eat things left behind by carnivores and herbivores. Decomposers break down dead plant or animal matter into soil. Detritivores eat soil and other very small bits of organic matter.
