2.  An ecosystem is a community of living organisms and
their interactions with their abiotic (nonliving)
environment.
 The members of biotic components of an ecosystem
are grouped in to three based on how they get food.
•Producer (plants)
•Consumer (Animals)
•Decomposers (Micro-organisms)
ECOSYSTEM
Ecosystems can be small, such as the tide pools found near the rocky
shores of many oceans, or large, such as the Amazon Rainforest in Brazil.

3.  A consumer is any animal that gets its energy from
consuming another organism.
 In many ecosystems, the bottom of the food chain
consists of photosynthetic organisms (plants and/or
phytoplankton), which are called primary producers.
 The organisms that consume the primary producers
are herbivores: the primary consumers.
 Secondary consumers are usually carnivores that
eat the primary consumers.
 Tertiary consumers are carnivores that eat other
carnivores. Higher-level consumers feed on the next
lower tropic levels, and so on, up to the organisms at
the top of the food chain: the apex consumers.
