The nature of the process and of the specialized structures developed for waste disposal vary greatly with the size and complexity of the organism. Excretion is a general term referring to the separation and throwing off of waste materials or toxic substances from the cells This shows excretion in Lower Organisms

Classification using the binomial method and classification of plants using agricultural methods and by life cycle

For Year 11 (SS 2) students. Explains all about Nutrition, modes and types, and also explain the biological function of macro and micronutrients

Although all heterotrophs feed on other organisms their method of feeding differs based on whether they are holozoic which includes carnivorous plants, parasitic organisms and saprophytic organisms, and the type of food that the organism feeds on.

The mechanism by which an organism obtains and utilizes the food materials to perform different metabolic activities is known as feeding mechanism

Marine habitat is habitat that support marine life. Marine life depends in some way on the saltiness of water that is in the sea (the term marine comes from the Latin mare, meaning sea or ocean). A habitat is an ecological or environmental area inhabited by one or more living species. The marine environment supports many kinds of these habitats.

An Aquatic Ecosystem is an ecosystem in a body of water. An Estuarine habitat is a dynamic ecosystem having a connection to the open sea through which the sea water enters with the rhythm of the tides.

Habitat is not necessarily a geographical area, it can be anywhere that living organisms dwell. Organisms that live in water are called Aquatic organism. Some dwell in Fresh water, that is water that does not have salt in it.
