level of organization in plant and animal

Introduction - Every organism whether plant or animal is unique in itself. There is a wide diversity in the flora (plants) and fauna (animals) in the worl..

Pesticides, detergents, chemical dyes and other industrial chemicals and their waste constitute synthetic organic compounds. When present in water, these chemicals can act as toxic poisons for plants, animals and humans. Such chemicals enter the hydrosphere either by ..

Summary - The cells of all living organisms consist of protoplasm, which is bound by a cell membrane. Prokaryotic cells and cells of algae, fungi and higher plants contain a cell wall outside the cell membrane. Some protozoans cells show the presence of a cell coat outside the c..

Animals are heterotrophs i.e. they are incapable of synthesizing their own food. They depend on plants and other animals for food. Man also being a heterotroph, gets his food from plants as well as animals..

Insectivorous plants are autotrophic but obtain organic matter and animal nitrogen from insects, however not bigger than the size of a grasshopper. There are about 450 species of insectivorous plants..

They are said to be partly autotrophic and partly heterotrophic. These autotrophs supplement their nutritional requirements by trapping and digesting insects and other small animals. The trapped insects are killed and their proteins are digested by proteolytic enzymes secreted by the epi..

The animal kingdom includes eukaryotic multicellular organisms which exhibit heterotrophic nutrition. They are commonly known as animals and differ characteristically from the other major groups of plants, in their capacity to be able to mov..

Acid rain chemically strips waterways of necessary nutrients and lowers the pH to levels where plants and animals cannot live. Most of the aquatic animals cannot survive when the pH is less than 4. Some species of fish, such as salmon, die even when the pH i..

An organism is a distinct unit of life in nature. It is said to be the smallest level and basic unit of ecological hierarc..
