Ecology and Environment - Inter-Relationship of Living Organisms
Ecology is the scientific study of the inter-relationship of living organisms in their environment, encompassing abiotic and biotic influences. The environment includes all factors affecting organisms, creating conditions for survival. The interdependence of plants, animals, and microbes with their surroundings is crucial for understanding ecosystems and the biosphere.

Presentation Transcript
ECOLOGY AND ENVIRONMENT LIFE DOES NOT OCCUR IN A VCACUUM EVERY LIVING ORGANISM IS SURROUNDED BY MATERIALS AND FORCES. FOR ITS SURVIVAL, A PLANT, AN ANIMAL, OR A MICROBE CAN NOT LIVE COMPLETELY SEALED IN AN WATER-RESISTANT SKIN OR SHELL. EACH LIVING ORGANISM HAS TO DEPEND AND ALSO TO INTERACT WITH DIFFERENT ABIOTIC AND BIOTIC COMPONENTS
The Abiotic Components WATER CARBON DIOXIDE CALCIUM OXYGEN, CARBONATES PHOSPHATES AN ARRAY OF ORGANIC COMPOUNDS
THE BIOTIC COMPONENTS PLANTS, ANIMALS MICROBES
WHAT IS ECOLOGY ? Ecology is the scientific study of the inter- relationship of living organisms Ecology mainly concerned with the directive influences of abiotic and biotic environmental factors. Above all ecology is the science which investigates organisms in relation to their environment
WHAT IS ENVIRONMENT? The term Environment , which etymologically means - surroundings . The environment includes other living things, temperature, wind, electricity etc. Environment consists of both biotic and abiotic substances. Environment creates favourable conditions for the existence and development of living organisms.
Environment is a very broad concept. Everything that affects an organism during its lifetime is collectively called its environment . The inter-dependence and interrelationship of living organisms - plants, animals and microbes with each other and with their physical environment may be expressed in the next slide
FOREST Each trees- organism Together all trees- Population Plants and animals- Community Ecosystem A costal Ecosystem Organisms & Their Environment The Biosphere Entire Ecosystem
The abiotic environment is linked to living organism in terms of energy flow and' various bio-geochemical cycles. So, living organisms depend upon air, water and land for their survival and entire unit is responsible for the existence of living organism or biosphere Conclusion Thus the environment is the sum of all these living and non-living things. And Ecology is the scientific study of their mutual relationship. That is why ancient Indians believed nature/Earth as Mother .
