What organism is the highest on the food chain?

species at the top of the food chain, with no predators of its own. Also called an alpha predator or apex predator. one of three positions on the food chain: autotrophs (first), herbivores (second), and carnivores and omnivores (third).

What is the example of food chain?

Food Chain. A food chain shows you how one organism eats another and transfers its energy. For example, a zebra eats grass, and the zebra is eaten by the lion.

What is food chain give two examples?

A food chain is a linear network of links in a food web starting from producer organisms and ending at apex predator species, detritivores, or decomposer species. eg. Next come organisms that eat the autotrophs; these organisms are called herbivores or primary consumers — an example is a rabbit that eats grass.

What are organisms in a food web?

All species in the food webs can be distinguished into basal species (autotrophs, such as plants), intermediate species (herbivores and intermediate level carnivores, such as grasshopper and scorpion) or top predators (high level carnivores such as fox) (Figure 1). These feeding groups are referred as trophic levels.

Where is the largest amount of energy found in this food web?

producers
The first trophic level of the food chain has the most energy. This level contains the producers, which are all of the photosynthetic organisms.

Why does organism eat another organism?

A heterotroph is an organism that eats other plants or animals for energy and nutrients. The term stems from the Greek words hetero for “other” and trophe for “nourishment.” Organisms are characterized into two broad categories based upon how they obtain their energy and nutrients: autotrophs and heterotrophs.

Why do organisms eat other organisms?

What is food chain with example and diagram?

A food chain is a linear diagram showing how energy moves through an ecosystem. It shows only one pathway out of the many possibilities in a specific ecosystem.

What is food chain and food web with example?

A food chain only follows just one path as animals find food. eg: A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass. A food web shows the many different paths plants and animals are connected. eg: A hawk might also eat a mouse, a squirrel, a frog or some other animal.
