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

ecology

The term ecosystem was first coined by

Sir Arthur George Tansley

The environment involves both

living organisms and the non-living physical conditions

For food shelter growth and development all life systems interact with the environment. Environment is a

life supporting system

The environment in which a particular organism life is called its

habitat

The role of an organism in habitat is called its

niche

This ecosystem are exclusively land based ecosystem. There are different types of this ecosystems distributed around various geological zones

terrestrial ecosystem

It consists of several plants, animals and microorganisms that live in a coordination with the abiotic factors of the environments. It helps in maintaining the temperature of the earth and we are the major carbon sink

forest ecosystem

Vegetation is dominated by grasses and herbs. Temperate grasslands, savanna grasslands, are some of the example of this ecosystem

grassland ecosystem

This ecosystem are the void of trees and are found in cold climates or were rainfall is scarce. These are covered with snow for most of the year. The ecosystem in the arctic or mountain tops is blank type

tundra ecosystem

Deserts are found throughout the world. These are regions with very little rainfall. The days are hot and the nights are cold

desert ecosystem

This systems are presented in a body of water. This can be further divided into two types there are the freshwater ecosystem and the marine ecosystem

aquatic ecosystem

These ecosystem is an aquatic ecosystem that includes lakes bonds rivers streams and wetlands. These have no self content in contrast with the marine ecosystem

freshwater ecosystem

This ecosystem includes seas and oceans. These have a more substantial salt content and greater biodiversity in comparison to the freshwater ecosystem

marine ecosystem

It is the ultimate source of energy on earth

sun

The flow of energy from a producer to a consumer and eventually to an apex predator or a detritivore is called a

food chain

An ecological pyramid is the blank of the number of energy and biomass of the successive trophic levels of an ecosystem

graphical representation

He was the first ecologist to describe the ecological pyramid and its principles in 1927

charles elton

The biomass number and energy of organisms ranging from the producer level to the consumer level are represented in the form of a pyramid hence it is known as the

ecological pyramid

It is a network of interconnected food chains. It comprises all the food chains within a single ecosystem. It helps in understanding that plants lay the foundation of all food chains.

food web

The varied niches are blank and together make a balance ecosystem

interdependent

This component refer to all life in an ecosystem. Based on nutrition these components can be categorized in autotrophs, heterotrophs and saprotrophs or the decomposers

biotic components

Producers include all blank such as plants. They are called blank as they can produce food through the process of photosynthesis. Consequently all other organisms higher up on the food chain rely on producers for food

autotrophs

Consumers or blank are organisms that depend on the other organisms for food. Consumers are further classified into primary consumers secondary and tertiary consumers

heterotrophs

Rely on producers on food

primary consumers

Depend on primary consumers for food it can be carnivore or omnivore

secondary consumers

Consumers for food it can be omnivore

tertiary consumers

They are the pre-own tertiary consumers for energy

quaternary

It include saprophytes such as fungi and bacteria

decomposers

This component or the nonliving component of an ecosystem. It includes air water soil minerals sunlight temperature nutrients wind altitude turbidity etc

abiotic components

Some disruptions can be devastating for an individual species and make even cause an entire species to permanently disappear in a process called

extinction

Fire is a common disruptions to ecosystem that can be caused by nature or human behavior

wildfire

It can occur after a storm and maybe disruptive to an ecosystem depending on the extent of the flooding and how long the water stays

flooding
