Ecosystems Flashcards
What is used in sprinting?
Anaerobic respiration
What’s the word equation for anaerobic respiration in humans?
Glucose➡️lactic acid (+energy)
Word equation for anaerobic respiration in yeast (fermentation)?
Glucose➡️ethanol + carbon dioxide (+energy)
What is a niche?
A particular place or role an organism has within an ecosystem
Why do you keep breathing heavily when you finish exercising?
Because of oxygen debt - you need the extra oxygen to break down the lactic acid you have made
What is the word equation for photosynthesis
Carbon dioxide+water➡️oxygen+glucose
What are the four main minerals that a plant needs for growth
Nitrates, phosphates, potassium and magnesium
What is bioaccumulation
What we call the building up of toxic chemicals in the organisms of a food chain
If two organisms both depend on each other for something what are they called
Interdependent
In a food chain what do the arrows show
The flow of energy
What is the equation for aerobic respiration
Glucose+oxygen➡️carbon dioxide+water (+energy)
Where on the leaf does most of the photosynthesis take place
Palisade cells
What do we call the place where an animal or plant lives
Habitat
Where does the photosynthesis takes place
Chloroplasts
Where does aerobic respiration happen
In the mitochondria
What is fertiliser
Chemicals that are added to the soil to help plants grow
What is chlorophyll
The green pigment found inside chloroplasts that absorb light energy
What is photosynthesis
The process that plants and algae carry out to make their own food
What is the stomata
Tiny holes on the bottom of the leaf
Some bacteria can use energy released by chemical reactions to make their own food (glucose) what is this called
Chemosynthesis
