Detailed explanation-1: -A consumer is an organism that gains its energy by consuming, or eating, other organisms. Animals like grasshoppers, lizards, snakes, hawks, and humans are all have different diets, but are all consumers.
Detailed explanation-2: -There are four types of consumers: omnivores, carnivores, herbivores and decomposers. Herbivores are living things that only eat plants to get the food and energy they need. Animals like whales, elephants, cows, pigs, rabbits, and horses are herbivores. Carnivores are living things that only eat meat.
Detailed explanation-3: -Hawks are carnivores that eat toads. Therefore they are one trophic level higher than toads. They are considered tertiary consumers. Tertiary consumers are the 4th trophic level.
Detailed explanation-4: -Examples of primary consumers are zooplankton, butterflies, rabbits, giraffes, pandas and elephants. Primary consumers are herbivores. Their food source is the first trophic level of organisms within the food web, or plants.
