Food Web
What is a food web?
A collection of food chains that are interdependent and interlocking.
What are the 3 most important matter cycles
Carbon, nitrogen, water
What is the energy cycle?
The energy cycle describes the interactions between energy sources within the Earth's environment
What is an ecosystem?
An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life
What is a primary consumer
it is the first consumer after producers
What is the top of the food web/chain called?
Tertiary consumer
What is the matter cycle and what does it do?
Matter cycling is where matter moves from one form to another or from one place to another on the earth, and inside its ecosystems
Does energy cycle endlessly?
No, energy cannot be recycled indefinitely within a living system
What is the producers and how do they make their own food?
Plants and they make their own food through photosynthesis
How do animals effect the cycles of matter
Animals and decomposers consume matter for their life functions, continuing the cycling of matter.
Where does the energy in a food chain or web come from?
The sun
What is the carbon cycle and its importance in the ecosystem
The carbon cycle is how carbon moves around the world and is crucial for maintaining the balance of carbon in the atmosphere. This helps regulate the Earth's climate and provides the necessary carbon for plants to do photosynthesis
What forms an energy cycle?
The biogeochemical cycle which utilizes or releases energy through various biochemical processes such as respiration and photosynthesis is an energy cycle.
It will most likely destroy at least one cycle in the ecosystem
How do animals like termites help to cycle nutrients?
They feed on wood which releases nutrients such as carbon and nitrogen back into the soil
What are the most important producers in a food web?
Green plants, and some kinds of bacteria, are the most important producers
What human activity impact the cycling of nutrients in terrestrial and aquatic ecosystems?(name 1 or 2 of them)
Deforestation, agriculture, pollution, climate change, and urbanization
How does the energy flow through different trophic levels in an ecosystem, and what role does each organism play in the transfer of energy?
in an ecosystem, the energy flows from the sun to producers where they make energy for primary consumers such as herbivores which are then fed to secondary consumers. Lastly the tertiary consumers will eat them which will transfer energy.
How does the carbon cycle relate to ecosystems on land?
Plants on land and in the ocean convert carbon dioxide to biomass through photosynthesis
What is another word for consumers and or producers
Autotrophic is for producing and heterotropic is consumers.
How does climate change affect the stability and structure of food webs in different ecosystems?
One example is it can make changes to smaller phytoplankton species can lengthen the food-web, increasing assimilation losses and/or changing nutrient cycles.
What is another name for the matter cycle
Biogeochemical cycle
How much energy is transferred to another animal when consumed by another
10% of energy is actually transferred because the rest is lost as it turns into heat energy
What is biomagnification
It is when harmful substances are more concentrated in higher trophic levels
What is primary or secondary succession? (either of them work)
Primary is when an ecosystem is completely lifeless/ destroyed such as no soil and just all rock and then plants and animals will colonize to it which the ecosystem.
Secondary is the same as primary but it starts with soil.
