Explanation

A food chain always begins with producers.

It usually green plants or algae, that make their own food through photosynthesis.

Explanation

The stratospheric ozone layer is Earth's “sunscreen”  protecting living things from too much ultraviolet radiation from the sun.

Oxygen layer in the atmosphere

Ozone protects us from the harmful ultraviolet radiation of the sun.

Ozone formula: O3

The ozone layer lies approximately 15-40 kilometers (10-25 miles) above the Earth's surface, in the stratosphere.

The ozone layer is depleting: Air pollution

Explanation

The ultraviolet rays are filtered through Ozone Layer.

The ozone layer, often known as ozone shield is a part of Stratosphere.

Explanation

• The stratosphere is the layer of the atmosphere where the ozone layer is present.
• It extends from approximately 12 to 50 kilometers (7.5 to 31 miles) above the Earth's surface.
• The ozone layer is a critical component of the Earth's atmosphere, as it absorbs harmful ultraviolet (UV) radiation from the sun, protecting life on Earth.

Explanation

A point source of pollution is a single, identifiable source from which pollutants are discharged, such as a factory or industry.

Industries release waste directly into air or water from specific locations.

Explanation

Acid rain is called an "unseen plague" because its harmful effects on soil, water, and structures occur gradually and often go unnoticed at first.

It can silently damage ecosystems, corrode buildings, and acidify water bodies over years without immediate visible signs.

Explanation

Lithosere succession takes place on bare rocks. 

 "Litho" refers to "rock,"

So lithosere specifically describes the process of ecological succession that begins on exposed rock surfaces

Explanation

• The ozone layer in the stratosphere absorbs and restricts ultraviolet (UV) radiation from the sun.
• It protecting life on Earth from harmful UV rays.
