We find animals of certain kind living in particular climatic conditions because every living organism is adapted to live in the particular habitat. Every living thing develops their feature according to the area they live in.
For example, penguins have thick skin to protect themselves from cold and webbed feet to swim in water. It will not be able to survive in the hot climate of tropical regions as they developed thick skin for the protection from cold not from the hot and humid temperature.

In burning of wood, new substances are formed and hence it is a chemical change. While cutting the wood into small pieces no new substance is formed, thus it is a physical change.
Hence, burning of wood and cutting it into small pieces are considered as two different types of changes.

A storm is a disturbed state of environment creating severe weather conditions mainly high speed winds. A thunderstorm is a storm with sound and lightning and typically also heavy rain or hail.
- Thunderstorms develop in hot and humid areas.
- High temperature in this areas cause hot humid (with water vapours) air to rise up. So, strong upward rising winds with water droplets are generated.
- At high altitude, these water drops freeze and fall again towards earth.
- Upward movement of air and downward movement of water drops, together, cause lightning and sound.

Ingestion: The intake of food is called ingestion. Method of ingestion, i.e. taking of food, varies from one animal to another.
Egestion: Removal of waste materials from the body is called egestion. The faecal matter is removed through the **** from time-to-time. Since the waste of food left after digestion is also called faeces, hence the process of egestion is also known as defecation.

The food that we consume are not in a form that the body can use as nourishment. Our food and drink must be changed into smaller molecules of nutrients before they can be absorbed into the blood and carried to cells throughout the body. Digestion is the process by which complex food materials are broken down into simple ones, so that they can be easily absorbed and transported to all parts of the body. Now it is possible for our body to use them to build and nourish cells and to provide energy.
The energy cannot be stored because it is for utilization.The form in which energy is stored in the cell is ATP.

The gall bladder temporarily stores bile.
Liver (the largest gland in human body) secretes bile juice that is stored in a sac called the gall bladder. The bile helps in the digestion of fats.
The bile plays an important role in the digestion of fats.The pancreas is a large cream coloured gland located just below the stomach.The pancreatic juice acts on carbohydrates, fats and proteinsand changes them into simpler forms.The partly digested food now reaches the lower part of the small intestine where the intestinal juice completes the digestion of all components of the food. The carbohydrates get broken into simple sugars such as glucose, fats into fatty acids and glycerol, and proteins into amino acids.

Eutrophication is the process in which a water body becomes overly enriched with nutrients, leading to plentiful growth of simple plant life. The excessive growth (or bloom) of algae and plankton in a water body are indicators of this process. Eutrophication is considered to be a serious environmental concern since it often results in the deterioration of water quality and the depletion of dissolved oxygen in water bodies. Eutrophic waters can eventually become “dead zones” that are incapable of supporting life.
Eutrophication may be defined as the inorganic nutrient enrichment of natural waters, leading to an increased production of algae and macrophytes. Many lakes are naturally eutrophic and in some cases there is a progressive eutrophication as the lake matures. The term Eutrophication is more widely known in relation to human activities where the artificial introduction of plant nutrients has led to community changes and a deterioration of water quality in many freshwater systems. This aspect has become increasingly important with increases in human population and more extensive development of agriculture and eutrophication now ranks with other major anthropogenic effects such as deforestation, global warming depletion of the ozone layer and large scale environmental disturbance in relation to its potentially harmful effect on natural ecosystems.
