A greenhouse gas (sometimes abbreviated GHG) is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect. The primary greenhouse gases in the Earth's atmosphere are water vapour, carbon dioxide, methane, nitrous oxide, and ozone.

Forest is a renewable resource.

Deciduous means “falling off at maturity” “ or “tending to fall off”. It is typically used in order to refer to trees or shrubs that lose their leaves seasonally most commonly during autumn and to the shedding of other plant structures such as petals after flowering or fruit when ripe.

Common examples of deciduous trees include oak, maple, and hickory trees.

There are different types of interactions in the biotic community. Frog feeds for snakes. Snakes are the main predators of frogs.

The control over a prey is determined by the level of competition faced by other predators. If the same prey is prey to other predators, the control is considered to be lesser.

In ecology and biology, abiotic components (also known as abiotic factors) are non-living chemical and physical factors in the environment, which affect ecosystems. Abiotic phenomena underlie all of biology.

From the viewpoint of biology, abiotic factors can be classified as light or more generally radiation, temperature, water, the chemical surrounding composed of the terrestrial atmospheric gases, as well as soil.

The macroscopic climate often influences each of the above. A renewable resource is a natural resource with the ability to reproduce through biological or natural processes and replenished with the passage of time. Renewable resources are part of our natural environment and form our ecosystem.

Part of the Earth’s surface and atmosphere that contains the entire terrestrial ecosystem, and extends from ocean depths to about six kilometers above sea level. Not precisely demarkable, it contains all living organisms and what supports them soil, subsurface water, bodies of water, air and includes hydrosphere and lithosphere.

During summer, the Bay of Bengal is subject to intense heating, giving rise to humid and unstable air masses that produce cyclones. Widespread death and property destruction are reported every year in exposed coastal states such as Andhra Pradesh and Odisha.

Although cyclones affect the entire coast of India, the East Coast is more prone compared to the West Coast. Out of the cyclones that develop in the Bay of Bengal, over 58 per cent approach and cross the east coast in October and November.

Only 25 per cent of the cyclones that develop over the Arabian Sea approach the west coast. In the pre-monsoon season, corresponding figures are 25 per cent over the Arabian Sea and 30 per cent over the Bay of Bengal.

Biomes are climatically and geographically defined as similar climatic conditions on the Earth, such as communities of plants, animals, and soil organisms, and are often referred to as ecosystems. Some parts of the earth have more or less the same kind of abiotic and biotic factors spread over a large area, creating a typical ecosystem over that area.

Such major ecosystems are termed biomes. Biomes are defined by factors such as plant structures (such as trees, shrubs, and grasses), leaf types (such as broadleaf and needleleaf), plant spacing (forest, woodland, savanna), and climate. Major biomes include deserts, forests, grasslands, tundra, and several types of aquatic environments. Each biome consists of many ecosystems whose communities have adapted to the small differences in climate and the environment inside the biome.

The biosphere is the global ecological system integrating all living beings and their relationships, including their interaction with the elements of the lithosphere, geosphere, hydrosphere, and atmosphere. It is termed the zone of life on Earth.

Sanitary landfills are low lying sites where waste is isolated from the environment until it is safe. It is considered when it has completely degraded biologically, chemically and physically. In high-income countries, the level of isolation achieved may be high.
