What is the food chain like in Antarctica?

In the competitive Antarctic food chain, the food is abundant, but getting to it can be the hardest part. While the petrel species tend to make shallow dives, the larger birds are pirates and often steal food from feeding chicks or other birds.

What is a parasitic food chain?

Parasitic Food Chain Definition Parasitic food chain is a type of food chain that starts from herbivore, but the food energy transfers from larger organisms to smaller organisms, without killing in case of a predator.

What is an example of a food chain?

Each food chain is a possible pathway that energy and nutrients can follow through the ecosystem. For example, grass produces its own food from sunlight. A rabbit eats the grass. A fox eats the rabbit.

What is the food chain in the ocean?

This starts a whole new food chain. Different habitats and ecosystems provide many possible food chains that make up a food web. In one marine food chain, single-celled organisms called phytoplankton provide food for tiny shrimp called krill.

Is a bird a secondary consumer?

Luckily, secondary consumers have adapted to exist in every type of ecosystem. Temperate regions are home to moles, birds, and other secondary consumers such as dogs and cats. Long ago, even humans were considered secondary consumers because other mammals could easily hunt them.
