Over a period of time, many habitats change with respect to the types of plants and animals that live there. This change is known as succession.

Succession occurs because plants and animals cause a change in the environment in which they live. The first weeds and grasses that appear on a bare field, for example change the environment by shielding the soil from the direct sunlight. As these plants spread, the ground surface becomes cooler and moisture than it was originally. Thus, the environment at the ground surface has been changed. The new surface conditions favor the sprouting of shrubs. As shrubs grow, they kill the grasses by preventing light from reaching them and also build up the soil in the area. In addition, they attract animals that also enhance the soil. Pine seedlings soon take hold and as they grow, they in turn shade out the shrubs. They are not able to shade out oak and hickory seedlings, however, they have found the forest floor suitable. These seedlings grow into large trees that eventually shade out the pines.

GREEN ENERGY

Fossil fuels are used to generate the majority of the world's energy, and they come from in different forms. For example, coal may be burned in a power (21)            to generate electricity, but gasoline burned in a car’s engine to make it fun. Neither of these two sources is considered but gasoline is green energy because they produce a lot of pollution when they are burned. In addition, they come from a source that is inevitably going to (22)            .

Green energy can be defined as any energy source that is to some degree non-polluting. When it is called (23)             , this means that a person can replace the same amount of energy that was consumed by that person (24)            that person's lifetime. Since it took millions and millions of years to create the fossil fuels that we now burn, we know that they cannot be replaced by us.

Wind power and solar power, (25)            harnessed properly, are two excellent sources of green energy. Once the necessary parts such as wind turbines to generate wind power and solar panels to create solar power have been produced, only the pollution from the production is left.

For example, coal may be burned in a power (21)             to generate electricity, but gasoline burned in a car’s engine to make it fun.
