COMPONENTS OF AN ECOSYSTEM

COMPONENTS OF AN ECOSYSTEMECOSYSTEMEcological System composed of interdependent living (biotic) and non-living (abiotic) components enclosed within a definite boundaryEcosystems vary in kind and size.There is interaction between the biotic components and abiotic components in an ecosystem.

What living things exist in particular ecosystems?BIODIVERISTY IN ECOSYSTEMSHabitat the place where large groups of plants and animals live at the same timeLarge ecosystems like the forest and the sea are habitats for a variety of plants and animalsBiodiversity is a common characteristic of all ecosystems.The Philippine forests is reported to be one of the most diverse forests in the world.Can you give examples of ecosystems and habitats?

What are the reasons for the disappearance of life in our forests?

Apply itAn aquarium can be considered an ecosystem. List down the abiotic and biotic components of the aquarium ecosystem.ABIOTIC

Can you give examples more examples of interactions in the ecosystem?

Producers, Consumers, DecomposersProducer plant that can make its own food to supply the matter and energy to it needs to survive. (Examples: plants, algae, tress, etc.)Producers RolesProduce oxygenSupply foodProvide shelterConsumer organism that feeds on or consumes other organisms.Types of ConsumersHerbivore animals that eat plants (moose, aphids)Carnivore - animals that eat mostly meat (trout, wolf)Omnivore - animals that eats both plants and meat (human, bear)Scavenger animals that feeds off remains of dead (vultures, hyenas)Decomposer decompose (break down) dead plants or animals (fungi)Producers, Consumers, DecomposersPrey animal that is hunted for foodPredator animal that hunts and consumes preyExample: coyote and deerWhich one is the predator?CoyoteWhich one is the prey?DeerDecomposers are organisms involved in rotting or in the process of decompositionFood ChainFood Chain feeding interactions between producers and consumersAn organism may be a part of several food chains. This complex relationship is called food web.

Energy TransferEnergy goes from the sun to producers, to herbivores, and omnivores, and then to carnivore and omnivoresEach consumer, regardless of the level it occupies in the pyramid, retains only about one-tenth of the energy of what it has consumed.The remaining bulk of energy (9/10) is used up in the process of actual living.The energy flow in an ecosystem is unidirectional. Once energy has been used up, it cannot be recycled.What happens to this energy?Most of it is dissipated as thermal energy.

Cycle of matterThere are other materials in the environment on which organisms depend on to survive. These are your elements.
