Question

In nature, all green plants are ___________ whereas animals are consumers.

Answer 1

Organism in an ecosystem, or biome, relies on other organisms and also the physical environment. Plant and animal species need each other for food and rely upon the environment for water and shelter.

Complete answer: Food chain refers to a sequence of events in an ecosystem, where one organism eats another and is eaten by another organism. It starts with the first source, just like the Sun, then producers make food, continues with consumers, or animals who eat the food, and ends with the highest predator.
Producers are represented primarily by green plants, and photosynthetic bacteria. Consumers include herbivores, carnivores, etc.
A food chain has a subsequent structure:
Producers → Primary consumers (herbivores) → Secondary consumers (primary carnivores) → Tertiary consumers (Secondary carnivores)
Common features of the food chain:
a.Plants manufacture their own food and so, are at the initial level of all food chains.
b.Food chains are complicated and every chain has side branches. Each branch divides thus complicating the food chain.
c.The link in a very organic phenomenon is sometimes three. As we move ahead within the organic phenomenon, the dimensions of predators progressively increase. Finally, a stage is reached when the predator becomes so large in size that it can now not be preyed upon.
Types:
1. Food chains on land: Organisms like bacteria, maggots go after the death and break them down into nutrients that keep the food chain going. By eating and excreting, decomposers return the nutrients of dead organisms to the soil, which nourishes the plants and hence the food chain starts everywhere again.
Examples:
Hazel tree - mouse - bird of night
Herring - salmon - bear
Juniper berries - rabbit - fox
Leaves - ants - anteaters
Leaves - caterpillars - birds – snakes
2. Food chains in water: Food chains in water-based environments are complex. Decomposers distribute nutrients throughout the water column, feeding the plankton that forms the bottom of all aquatic food chains.
Examples:
Insect - fish - humans
Plankton - shrimp - herring - cat
Plankton - snail - mackerel - shark
Plankton - snail - tuna - dolphin
Caterpillars - turtles - alligators – humans

Note: Food chain is divided into different trophic levels. Producers are initially trophic level, the first consumers at second and it goes on. Also, a selected organism may often occupy different trophic levels of a food chain. For instance, kith and kin eat grains or furthermore because the flesh of the goat feeds on the plant, thereby occupying two different trophic levels at the identical time.
