Is the science that deals with the relationships between living organisms with their physical environment and with each other.

Ecology

Short for :ecological system", Is a community of living organisms (plants, animals and microbes) in conjuction with nonliving components of their environment (things like air, water and mineral soil), interacting as a system. These biotic and abiotic components are linked together through nutrient cycles and energy flows.

Ecosystem

Is based on land and consists of biomes

Terrestrial Environment

Are subset of Earth's aquatic ecosystem

Freshwater Environment

Is characterized by saltwater and may be divided broadly into the shallow waters of the continental shelf composing the neritic zone.

Oceanic Marine Environment

The deeper waters of the ocean that constitute the oceanic region.

Oceanic Region

Which views ecosystems as large units

Ecosystem Ecology

Which attempts to explain ecosystem behavior from the properties of individual units.

Population Ecology

Are those that are existing in nature; they are further classified into terrestrial and aquatic.

Natural Ecosystem

Are simple, human-made, unstable and subjected to human intervention and manipulation.

Artificial Ecosystem

Extract nutrients from soil or ocean and manufacture their own food using photosynthesis, in the presence of carbon dioxide and sunligh and so energy from sun powers the base of food chain.

Producers

An exception occurse in deep-sea hydrothermal ecosystems where their is no sunlight. Here, the primary producers manufacture foo through a process called

Chemosynthesis

Are organisms that obtain nutrients by consuming other organisms.

Consumers

Is an organism that cannot synthesize their own foor and must obtain it ready made.

Heterotroph

Animals who derive their required energy directly from consuming the plants and plants only. Also known as primary consumers.

Herbivores

Animlas that feed on other animals.

Carnivores

Animals that feed on both plants and animals.

Omnivores

It consumes dead organic material such as cacasses, fallen leaves, dead plants, animals droppings and shed skins. This waste contains nutrients which are thus returned to the soil, facilitating new plant growth, or made easier for other organisms to consume. By breaking down dead matter into smaller peices, detritivores speed up the process of decomposition.

Detritivores

This group of functions relates to the capacity of natural and semi-natural ecosystems to regulate essential ecological processes and life support systems through bio-geochemical cycles and other biospheric processes. In addition to maintaining the ecosystem (and biosphere health), these regulatory functions provide many services that have direct and indirect benefits to humans

Regulatory Functions

Natural ecosystems provide refuge and reproduction habitat to wild plants and animals and thereby contribute to the conservation of biological and genetic diversity and the evolutionary process. It supports different food chains.

Habitat Functions

Photosynthesis and nutrient uptake by autotrophs converts energy, carbon dioxide, water and nutrients into wide variety of carbohydrate structures which are then used by secondary producers to create an even larger variety of living biomass. Production of wide range of goods ranging from food to raw materials.

Production Functions

Ecosystem provide an essential "reference function" and contribute to the maintenance of human health by providing opportunities for spiritual and religious values, Education and inspiration, cognitive development, recreation, aesthetic experience.

Informational Functions

These are micro-organsims which break-down organic matter into inorganic compounds adn derive their nutrition in the process.
