1. Ecology - c) The study of how living things interact with each other.
Explanation: Ecology is the scientific study of the relationships between living organisms and their environment, including the interactions between individuals, populations, communities, and ecosystems.

2. Environment - h) It means simply what is around us.
Explanation: The environment refers to the surroundings or conditions in which a person, animal, or plant lives or operates. It includes both natural and man-made elements, such as air, water, land, buildings, and other living organisms.

3. Flora - i) All the plants that grow in a region.
Explanation: Flora refers to the plant life or vegetation found in a particular region or ecosystem. It includes all types of plants, from trees and shrubs to flowers and grasses.

4. Fauna - j) The animals of a region.
Explanation: Fauna refers to the animal life or collection of animal species found in a particular region or ecosystem. It includes all types of animals, from mammals and birds to insects and reptiles.

5. Habitat - g) A place that provides animals and plants with food, water, and shelter.
Explanation: A habitat is a specific place or area where a particular plant or animal species naturally lives and obtains the necessary resources, such as food, water, and shelter, for survival and reproduction.

6. Pollution - е) When the land, sea or air becomes dirty or poisonous.
Explanation: Pollution refers to the introduction of harmful or undesirable substances or contaminants into the environment, including the land, water, and air. It can be caused by human activities, such as industrial processes, transportation, and waste disposal.

7. Carbon dioxide - a) A gas in the atmosphere. The gas that we breathe out.
Explanation: Carbon dioxide is a colorless and odorless gas that naturally occurs in the Earth's atmosphere. It is produced by various natural processes and is also a byproduct of human activities. Plants use carbon dioxide during photosynthesis, and humans and other animals exhale it during respiration.

8. Greenhouse effect - b) The Earth is becoming warmer because there is too much carbon dioxide in the atmosphere.
Explanation: The greenhouse effect refers to the process by which certain gases, including carbon dioxide, trap heat from the sun in the Earth's atmosphere. This trapping of heat leads to an increase in the Earth's temperature, causing global warming and climate change.

9. Ozone layer - d) This is the atmosphere between 10 km and 60 km above the Earth. The ozone stops a lot of the ultraviolet radiation from the sun.
Explanation: The ozone layer is a layer of ozone gas located in the Earth's stratosphere, approximately 10 to 60 kilometers above the Earth's surface. It plays a crucial role in protecting life on Earth by absorbing most of the sun's harmful ultraviolet (UV) radiation.

10. Ultraviolet radiation - f) Part of sunlight.
Explanation: Ultraviolet (UV) radiation is a type of electromagnetic radiation that is part of the energy produced by the sun. It is invisible to the human eye but can cause various biological effects, including sunburn, skin aging, and an increased risk of skin cancer.
