The Environment & Climate

What is an environment?

• everything that is around us, which includes both living and nonliving things

• Only Non-living things in our surrounding

• Only living things in our surrounding

• Oxides of sulphur and nitrogen are emitted into the atmosphere by combustion of fossil fuels.

What are the TWO main types of ecosystems?

What is an ecosystem?

• Animals and plants in the environment

• everything that is around us, which includes both living and nonliving things such as soil, water, animals and plants, which adapt themselves to their surroundings.

• consists of all the organisms and the physical environment with which they interact. 

• Oxides of sulphur and nitrogen are emitted into the atmosphere by combustion of fossil fuels

What is natural ecosystem?

What is Artificial ecosystem?

• consists of all the organisms and the physical environment with which they interact. 

• It includes all living organisms such as animals, birds, forests, insects, reptiles and microorganisms like algae, bacteria, fungus, viruses,

• It includes all non-living components such as air, cloud, dust, land, mountains, rivers, temperature, humidity, water, water vapour, sand, etc.

• is an artificial environment which is created and maintained by man.

What are the differences between Biotic environment and Abiotic environment?

• Biotic environment–It includes all non-living organisms and Abiotic environment– It includes all living components

• Biotic environment–It includes all living organisms and Abiotic environment– It includes all non-living components

• Biotic environment–Is natural and Abiotic environment– It is artificial

• There are no differences

Examples of Biotic environment are :

• Acid rain

• air, cloud, dust, land,

• Air pollution

• birds, forests, insects, reptiles

Why is the environment important?

There are different types of human activities which are directly attributed to the environmental disasters including

• Overpopulation

• Deforestation

• Depletion of ozone layer

• Human activities don't impact the environment

How does Human activities affect the environment?

• Increase population: Since more population means more land and more land means more destruction

• The answer is not there

• Ozone Depletion: One of the major problems caused by air pollution is the depletion of the Ozone layer which has given rise to global warming.

• Recycling
