ENVIRONMENT- It refers to the complete range of
physical and biological conditions in which org. like and
interact with biotic and abiotic factors.
ECOSYSTEM: All the interacting organisms in an area together
with the non-living constituents of the environment form an
ecosystem. E.g. forest, pond etc.
The ecosystem which exist Man-made ecosystem are
in nature on its own. e.g., called artificial ecosystem.
forest, lake, ocean. e.g., crop field, aquarium,
garden.
note- Agro-ecosystem is the largest man-made ecosystem.
other examples are aquariums, botanical gardens, parks, field crops, etc.

1. Biotic component: It includes three types of organisms :
(a) Producers: All green plants, blue green algae can produce their food (Sugar
and starch) from inorganic substance using light energy (Photosynthesis).
Therefore, all green plants are called producers. They are also called autotrophs.
