Biotic Community

Biotic Community A biotic community is an aggregate of populations of different species living together in an area or a habitat.For example the population of house flies,dogs,cats,human beings and mango trees.

Stable biotic community A

stable biotic community includes; Producer;-the green plants.  Consumers;-Human being ,animals and insectivorus plants,non green plants.  Decomposer;-the micro-organisms.

INTERACTIONS IN BIOTIC COMMUNITY  Three

types of interactions are found in a  Biotic community ,such as mutualism,commensalism,and parasitism .

Ecosystem 

 



Ecosystem is an aggregate of communities and the physical environment in which they live . It comprises two components, the Biotic components and The Abiotic components. BIOTIC components;-these are living components. these are green plants , the producers and animals, the consumers. The abiotic components are light temperature water and soil.

FOOD CHAIN  

The interdependence amang organisms is Studied as food chain..Food chain involves flow of energy .The simplest food chain has three links:eaten by eaten by

Producers

Herbivore

Carnivore

(plants)

(animals)

(animals)

Food chain;-the simplest food chain  In

this chain the green plants are producers, they trap solar energyand convert it into chemical energy.This energy is transferred To herbivore animals,the primary consumer through food . The carnivores or the secondary consumers are at the top of the chain as they feed on herbivore animals .

Exercise Q-Define the term Biotic Community. Q-Which are the producers ? Q-What is a primary consumer? Q-What is a secondary consumer .? Q-Define Biome. Q-Define a simple food chain. Q-What is an ecosystem .
