1. A pond ecosystem works with the natural environment to provide food and protection to the wildlife and plants it supports. Fish nibble on the plants and algae, producing waste that is broken down and absorbed as nutrients by the plants.
2 . Tropical evergreen forests are dense, multi-layered, and harbour many types of plants and animals. These forests are found in the areas receiving heavy rainfall (more than 200 cm annual rainfall). They are very dense. Even the sunlight does not reach the ground.
4. Deciduous plants lose their leaves to conserve water or to better survive dry weather conditions. Thus they regrow new foliage during the next suitable growing season.
5.The Mojave Desert occurs further south and covers the southern part of Nevada and part of California but elements of it extend into Arizona where it blends into the Sonoran Desert. Again, it is classed as a cold desert because of the low winter temperatures.
6.Penguins are only found in the Southern Hemisphere. The greatest concentrations are on Antarctic coasts and sub-Antarctic islands. There are 18 species of penguins, 5 of which live in Antarctica.
