Earths Ecosystems Flashcards
(21 cards)
An example of abiotic factor in an ecosystem is?
Bacteria 
What is the primary function of chloroplast in plant cells?
Photosynthesis.
A limiting factor for photosynthesis is?
Carbon dioxide, sunlight, water
What is the main purpose of the energy pyramid in ecosystem?
To show the flow of energy from producers to consumers.
What’s an autotroph?
Produce own food 
What’s a heterotroph?
Cannot produce its own nutrients.relies on others for nutrients.
What’s a producer?
First link in the chain.manufactures energy which is photosynthesis.
What’s a consumer?
All other organisms. 
What a decomposer?
Breaks down dead material into atomic form and return them into soil.
What’s a scavenger?
Organisms that feed on the dead animals.
How does the first traffic level supply energy to other consumers?
Their energies relied on to survive in this energy is passed on through the small animals to the big animals which they rely on each other gain that energy.
Photosynthesis is the process by which?
Plants use water and carbon dioxide to produce glucose. 
During respiration?
Organisms convert the energy and glucose into the energy carrying molecule ATP.
 The food web is…
A diagram that shows the transfer of energy from one organism to another in a ecosystem.
The intertidal zone is… 
A rocky shore which is only submerged during high tide 
Three specific parts of the leaf (adaptations) and details as to how they allow for photosynthesis to occur efficiently.
Waxy cuticle allows light in and prevent water loss. Palisade layer contains most chloroplast and main site of photosynthesis. Soma opens and closes as necessary and prevents water loss in hot temperature.
Aerobic respiration chemical equation 
C6H 1206 +602 -> 6C or 2+ H25 + ‘e’
Chemical equation for photosynthesis
6CO2 +6 H2O - sunlight / chlorophyll - C6H12O6 +6O2
Why are sunlight and chlorophyll placed above and below the arrow rather than being included in the reaction.
Sunlight in chlorophyll or catalyst and speed up the reaction but are not used in the reaction.
The rocky shore ecosystem
A- Zone B- Littoral C- Sub littoral D- Upper (high) E- Mid F- Low
Explain why organisms in zone A is different to organisms you can find in the sublittoral zone?
Organisms in Zone A need to survive without water and organisms in sublittoral Zone need to survive without air.
