CHAPTER 1 Flashcards
Are individuals that eat both plant and animal
Omnivores
animals that feed on plants and are primary consumers
Herbivores
what is the other term for decomposers?
micro - consumers
is the scientific study of living organisms ad their relationships with the environment.
Ecology
- are cells that create their own energy and biological materials from inorganic chemicals.
- are organisms that don’t need to eat because they make their own biological materials and energy.
Chemo autothrops
- are organisms that eat primary consumers for energy.
- They can either be carnivores or omnivores.
Secondary consumers
what is the other term for producers?
autothrops
are the living things that shape an ecosystem. Examples of this components include animals, plants, fungi, and bacteria.
BIOTIC COMPONENT
These are organisms that make their own food; they are also known as autotrophs .
- They get energy from chemicals or the sun, and with the help of water, convert that energy into useable energy in the form of sugar, or food.
PRODUCERS
What are the Three Types of Consumer?
- Primary Consumer
- Secondary Consumer
- Tertiary Consumer
- is an organism that feeds on primary producers.
- They are usually herbivores that feed on autotrophic plants, which produce their own food through photosynthesis.
Primary Consumer
who and when was the word “ecology” first used?
Ernst Haeckel in 1866
It is the field of biology that looks at our environment and what is going on in our environment.
Ecology
The biomes together with the aquatic ecosystems of the world are referred to as the:
biosphere
- animals that eat feed on other animals or meat eaters and they comprise the secondary consumers
Carnivores
What are the TWO components of the Ecosystem?
BIOTIC & ABIOTIC COMPONENTS
Ecosystems are either land-based (________) or water-based (_________).
land-based ( terrestrial ) or water-based ( aquatic ).
- These are organisms (such as bacteria, fungi and other microscopic) animals that derive energy and nutrients from dead and decaying matter and form its sub-system.
- They are also referred as micro consumers.
Decomposers
physical environment within species and between species
Ecosystem
consumers that feed on plants and are fed on by other organisms (also known as herbivores, carnivores or omnivores)
macro consumer
Organisms in the ecosystem that feed on plants or derive energy from the primary producers
Consumers
- is an animal that obtains its nutrition by eating primary consumers and secondary consumers.
- are carnivorous predators, although they may also be omnivores, which are animals that feed on both meat and plant material.
tertiary consumers
Macro consumers are called (________) since they depend on other organisms for their energy needs.
heterotrophs
It was coined from the Greek word “Oikos” meaning house and the Latin word “logos” meaning the “study of” – literally means
“study of nature’s household”.
