Lesson 5 Flashcards
Flow of Energy and Matter in Ecosystem (32 cards)
is a geographic area where organisms, climate, and topography work together to create a system of life
Ecosystem
topography work together to create a system of life. The two main categories of the ecosystem are the
Terrestrial ecosystem and Aquatic ecosystem
refer to all ecosystems found on land
Terrestrial ecosystem
Include all ecosystems found in the water
Aquatic ecosystem
include living organisms such as bacteria, fungi, plants, and animals
Biotic components
include all nonliving organisms such as energy, water, nutrients, air, temperature, humidity, salinity, and soil condition.
Abiotic components
The biotic components of an ecosystem can be classified into three categories
Producers, condusmers and decomposers
(also called autotrophs) are living organisms that produce their own food.
Producers
They use the energy from the sun to make food through photosynthesis, a process in which light energy is converted into chemical energy.
Producers
the dominant producers are green plants
in Terrestrial ecosystem
small photosynthetic organisms such as algae and phytoplankton are the common producers
in Aquatic ecosystem
(also called heterotrophs) are living organisms that directly or directly rely on producers for energy
Consumers
Generally, there are two types of consumers
Primary and secondary
eat primary consumers for energy
Secondary Consumers
(called herbivores) eat plants for energy.
Primary Consumers
can be carnivores or those that feed only on animals, or omnivores or those that feed on both plants and animals.
Secondary consumers
are living organisms that break down organic matter in plant and animal remains into useful substances.
Decomposers
The most common types of decomposers are
Bacteria
Fungi
Worms
The series of energy transfer from one organism to another is called
Food chain
describes who eats whom
Food chain
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
represents the available energy and population at each tropic level in an ecosystem
Ecological Pyramid
refers to the variety of living organisms on Earth at all levels of biological organization
Biological Diversity or biodiversity
is group a of individuals that share similar characteristics and are able to exchange genetic material for reproduction.
Species
