LIVING THINGS IN AN
ECOSYSYTEM

• An ecosystem is a community of living organisms (plants, animals and microbes) in conjunction with the non-living components of their environment (things like air, water and mineral soil), interacting as a system.

• A population is a summation of all the organisms of the same group or species, who live in the same geographical area, and have the capability of interbreeding.

This is a population of pandas

• In ecology, a community or biocoenosis is an assemblage or associations of populations of two or more different species occupying the same geographical area and in a particular time.
The term community has a variety of uses.

• THERE ARE MANY TYPES:
• Aquatic communities,terrestrial communities, discourse communities …

This is a aquatic community

INTERSPECIFIC RELATIONSHIPS
• The relationships between members of different populations are termed interspecific relationships. These interspecific relationships may be vital and lifelong or casual and temporary, or in between this range. These relationships constitute the biotic factors and may be beneficial, harmful or have no apparent effect on either population.

EXAMPLES
• This is an intraspecific relationship

INTRASPECIFIC RELATIONSHIPS
• Intraspecific relationships occur within species and are driven by competition for the same resources.
Intraspecific relationship can be divided into 2 categories cooperative and agonistic relationships.

• Scientists discuss some general ecosystem types. They call them biomes. A biome is a large area on the Earth's surface that is defined by the types of animals and plants living there.
