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.

Food chain, in ecology, the sequence of transfers of matter and energy in the form of food from organism to organism. Food chains intertwine locally into a food web because most organisms consume more than one type of animal or plant.

The majority of us don't actually know that there's a difference between food and nutrients. ... On the other hand, nutrition is a part of food that is used by our cells and metabolized by the body to make all the contributions that our body needs. Not all nutrients are acquired from food.

Differences: in natural ecosystems, recycling of minerals previously used by organisms is the most important source of nutrition, while in agroecosystems exogenous minerals are added, sometimes in large amounts, to compensate for that which leaves the ecosystem as the harvested crop.

Examples of primary consumers include zooplankton, ducks, tadpoles, mayfly nymphs and small crustaceans. Secondary consumers make up the third level of the food chain. Secondary consumers feed on smaller, plant-eating animals (primary consumers).

Levels of the food chain Within an ecological food chain, Consumers are categorized into primary consumers, secondary consumers, tertiary consumers. Primary consumers are herbivores, feeding on plants.

A food chain outlines who eats whom. A food web is all of the food chains in an ecosystem. Each organism in an ecosystem occupies a specific trophic level or position in the food chain or web. Producers, who make their own food using photosynthesis or chemosynthesis, make up the bottom of the trophic pyramid.

Explanation: Food chain refers to the chain of consumption of the organisms in the ecosystem and the overall contribution of this consumption to the ecosystem. ... Energy pyramid, refers to the "pyramid" of energy consumption. The pyramid is divided into groups and their amount of consumption and production of energy.

Carnivores specifically eat the flesh of other animals, typically muscle tissue. Predators kill and eat other organism to gain nourishment. Predation describes a type of feeding behavior , while carnivore describes a type of predation by the type of food consumed (i.e. flesh of animals).

Further trophic levels are numbered subsequently according to how far the organism is along the food chain. Level 1: Plants and algae make their own food and are called producers. Level 2: Herbivores eat plants and are called primary consumers.

Chemical nutrients and energy tend to flow in the same direction for most of an ecosystem. The big difference is that the chemical nutrients are ultimately recycled in the ecosystem while the energy is ultimately lost from the ecosystem to the universe at large. Energy in any ecosystem ultimately comes from the Sun.

Food Chains and Food Webs. A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another; the levels in the food chain are producers, primary consumers, higher-level consumers, and finally decomposers. ... Tertiary consumers are carnivores that eat other carnivores.

An ocean food chain shows how energy is passed from one living thing to another in the ocean. Producers make their own food (plankton, algae, seaweed), and consumers eat the producers and/or other consumers to get the energy they need (crabs, shrimp, dolphins, sharks and fish).

Food Chain: Plankton There are many species of plankton and each has a characteristic shape. Plankton may be phytoplankton (plant-like organisms - producers) or zooplankton (animal-like organisms - consumers). Loggerhead turtles eat plankton when they are very young and small juveniles. Clams also eat plankton.

Giraffes eat trees and bushes for food, and lions eat giraffes. Each link in a food chain is food for the next link. Food chains always start with plants and end with animals. Plants are at the bottom of the food chain.
