Ecology Flashcards
What is the definition of biotic?
living things and their remains in our ecosystem, rabbit/tiger
What is the definition of abiotic?
things in our ecosystem that are not alive rock, mud
What is the definition of biogeochemical cycles
the cycle of matter through abiotic and biotic organisms in our ecosystem
What are carnivores?
Organisms that eat strictly meat
What is cellular respiration?
The process in which sugar is converted to Co2 water and energy.
What is a consumer?
An organism that gains energy by eating other organisms.
what is a decomposer?
an organism that breaks down dead things such as animals
What is Ecology?
The general study of our ecosystem
What is an ecosystem?
All the living organisms and their physical and chemical environment, living components of the environment.
Ecosystem balance is?
The ability for the ecosystem to last. This keeps all chains and habitats sustainable.
Food chain?
A sequence of organisms in a line showing the transfer of energy and the feeding relationships
Food Web?
Eating relationships throughout a community
Herbivores are?
Organisms that consume strictly plant life
Omnivores?
Organisms that consume both plant life and meat
What is the process of photosynthesis?
The process where the suns energy is converted into chemical energy
Population?
The amount of organisms in a community
Producers are?
Organisms that produce there own food. Autotrophs
Scavengers are?
Animals that hunt for their food whether its already dead or not
Sustainability is?
An ecosystems capability to maintain a balance.
Trophic levels are?
The level of an organism in its ecosystem based off of its feeding relationship.
What is competition in an ecosystem?
When to animals have to compete for the same resources
What is a niche?
An organisms purpose in its ecosystem
Algae
Producer
Frogs
carnivore
Bacteria
Decomposer
Pine Tree
Producer
Human
Consumer, Omnivore
Vulture
Detritivore
Grasshopper
Herbivore
Detritivore
An animal that feeds on dead organic material
Bioaccumulation
The concentration of a substance in the body of an organisms
What is the word equation for respiration
Oxygen + glucose = H20 + carbon dioxide + energy
Where is the lithosphere located?
The ground level of our earth
What is the hydrosphere?
The part of the earth in which water is dominant
What is the atmosphere
The sky and area including clouds
In which sphere does life exist on the planet?
The biosphere
Where is the lithosphere located?
The ground level of our earth
What is the hydrosphere?
The part of the earth in which water is dominant
What is the atmosphere
The sky and area including clouds
In which sphere does life exist on the planet?
The biosphere
What is a terrestrial ecosystem
A land ecosystem
How is carrying capacity important in an ecosystem?
The carrying capacity is important because it shows how many organisms an ecosystems resources can support
If a wheat plant has 210KJ of energy and a mouse eats it, how much energy did the mouse consume
10% so 21KJ
Why is energy lost from one trophic level to the next
They prey utilizes 90% of the energy and you consume 10%.
