Reading Material: Realms of the Earth Astro-physicists and scientists believe that there could be quite a few planets in the Universe similar to our planet Earth. There is also a probable chance that some form of life prevails and sustains in one of such planet. However‚ so far as we presently know‚ the Earth is the only planet which supports life which makes it a very unique planet. It is therefore imperative (very important and necessary) for us to understand the spheres of the Earth as the spheres

(3) The Land Region: It is a tertiary set of units within a province. It indicates different land forms. (4) The Biome: It is an ecological unit and is found in biogeographic zones or provinces.Explanation

TUNDRA The Tundra is the coldest of all the Biomes and being situated in the extreme north of the planet has desert like conditions. It has extremely low temperatures‚ poor nutrients‚ and short growing seasons. There is a very low precipitation of less than five inches a year which is coupled with strong‚ dry winds. There is a very large annual amount of snowfall in the region which surprisingly is advantageous to plant and animal life as the snow provides and insulation layer on the surface of

growing and balanced. A biome is a geographical location usually large in area with a certain types of animals and plants. One example of a biome is the desert. The desert is very dry. The only plants that can survive are drought resistant like cactus. The only animals that live in the desert must be able to survive with very little or no water like the kangaroo who gets all the moisture it needs from solid foods and the camel that stores water in its hump. Other examples of biomes are the tundra‚ where

Ecology Ecology is the study of interactions between organisms and the living and non-living components of their environment. It involves collecting information about organisms and observing their life patterns as well. Ecology is a science that seeks to explain why patterns occur the way they do. Interdependence is a key component of biology‚ meaning that all the organism interact with one another in various ways. Its very crucial for organisms since they all depend on one another

A: An ecosystem is a natural unit consisting of all plants‚ animals and micro-organisms in an area functioning together with all the non-living physical factors of the environment. Among terrestrial ecosystems‚ the type that provides the most appropriate scale for understanding world distribution pattern is called a biome. Q2: What is an ecotone? A: A region of transition between two biological communities

1. Define ecology. Identify the two features of organisms studied by ecologists. Ecology is the scientific study of the interactions between organisms and the environment‚ which in turn determine both the distribution of organisms and their abundance. Ecologists study how interactions between organisms and the environment affect phenomena such as the number of species living in a particular area‚ cycling of nutrients in a habitat‚ and the growth of populations. 2. Describe the relationship between
