CONSUMERS

DEF: A consumers is an organism. They referred as Heterotrophs. They does not produce their own food. They eat other organism to get food.

CONSUMERS

Consumers are typically viewed as predatory animals such as the wolf and hyena. However, herbivorous animals and parasitic fungi are also consumers. Some carnivorous plants, like the Venus flytrap, are classified as both.

CLASSIFICATION

consumers are categorized into three types:

Primary consumers Secondary consumers Tertiary consumers

TYPES

Primary consumers are organisms that consume producers for energy and nutrients.

The producers in many recognizable ecosystems are plants.

The primary consumers are the herbivorous animals that consume the plants or grass.

PRIMARY CONSUMERS

Primary consumer are basically the herbivores of the ocean.

In Ocean, the primary consumers are lobster, mussules, and shrimp. Shrimp are still considered primary consumers

even though they eat phytoplankton, which are a producer rather than a plant.

This is because phytoplankton gets energy from the sun, not plants.

PRIMARY CONSUMER IN MARINE ECOSYSTEM

Herbivorus animals feeding on the leaves, grass and fruits of pro ducers are the primary consumers.

These are ants, flies, beetles, locusts, leafhoppers, bugs, spiders etc.

Among small animals, Squirrels, Flying foxes, cattles , rabbits etc are also primary consumers. 

PRIMARY CONSUMERS IN FOREST

secondary consumer is any carnivore that feeds on primary producers.

In more specific scientific language, the secondary consumer is an animal that resides in the second level of the food chain.

These animals are mostly carnivorous in nature and obtain energy by hunting and killing animals that primarily feed on the land.

Some secondary consumers feed mostly on dead animals.

SECONDARY CONSUMERS

 Secondary consumers include fish, whales and the friendly basking, and whale sharks.

They are the animals in the middle of the food chain. they eat plankton, shrimp and mollusks, which are primary consumers .

Basking sharks are friendly sharks, that do not have any teeth. They filter plankton and other krill into their enourmas mouth (left).

Basking sharks are the longest shark, however, a little bit smaller than whale sharks.

SECONDARY CONSUMERS IN OCEAN

BASKING SHARK

In the forest, secondary consumers(Omnivores) eat primary consumer (herbivores).

In the forest, secondary consumers are foxes, snakes, owls, etc.

SECONDARY CONSUMERS IN FOREST

Tertiary consumer are called omnivores.Its is at the top level of food chain at all trophic

level.They are also called scavangers.Tertiary consumers must eat other animals,

meaning they must be either carnivores or omnivores (meaning they eat both plants and animals).

Tertiary consumers cannot be herbivores because they are at too high of a level on the food chain.

TERTIARY CONSUMERS

 Tertiary consumers are the organisms that eat the secondary consumers, primary consumers, and sometimes producers.

Like Pelicans are birds of the sea. they eat a variety of small fish(herbivores or carnivores).

And like stingray is a ray, a flat fish with a tail and wings. Stingrays are bottom feeders, which means they eat stuff from the bottom side of their body, where the mouth is located.

TERTIARY CONSUMERS IN OCEANS

STINGRAY AND PELICAN

Tertiary consumer are called omnivores.In forest, tertiary consumer are  hawks, and

wolves, lions and bears.Lion feed on herbivores and carnivores like

cattle, foxes and others for food.
