ecosystem
The two main categories of the ecosystem are the
terrestrial ecosystem and the aquatic ecosystem.
refer to all ecosystems found on land, whereas aquatic ecosystems include all ecosystems found in water. Deserts and grasslands are types of ______, whereas oceans and lakes are types of aquatic ecosystems.
Terrestrial ecosystems
components
include living organisms such as bacteria,plants animals
Biotic
components include all nonliving organisms such. as energy, watesalinity, and soil condition.
abiotic
components or an ecosystem can be classifien sumers, an a decompo seroducers,
biotic
(also called autotrophs) are living organisms that produce their own food. Thei use the energy from the sun to make tooc throuer ho convented to rocemical energ light
Producers
the dominant producers are green plants, where in aquatic ecosystem, small photosynthetic organisms such as algae and phytoplankton phyto are the common producers.
terrestrial ecosystem,
are living organisms that break down organic matter in plant and animal remains into useful substances.
Decomposers
The most common types of ____ are bacteria, fungi, and worms.
Decomposers
In this ecosystem, animals such as zebras and gazelles are the primary _____whereas predators such as lions and cheetahs are the secondary consumers that prey on primary consumers. When the lions and cheetahs die, decomposers will eat their remains.
consumers of plants
A simple ____ in an aquatic ecosystem shows the flow of energy in a linear fashion (b) A food web represents a number of food chains interlinked together
food chain
The series of energy transfer from one organism to another is called
food chain
. The diet of some animals is not restricted to a certain plant or animal, Zebras may also consume other plant types, and lions may also prey on other carnivores, If the feeding behavior of each creature in a habitat will be traced, a number of interweaving food chains will be evident. This complex feeding relationship is called a
food web
