M2: Energy and Nutrient Relation Flashcards
(22 cards)
What are wavelengths which carry sufficient energy to drive light-dependent photosynthetic reactions?
Photosynthetically Active Radiations (PAR)
These are organisms (plants) that intake carbon dioxide during photosynthesis?
Photosynthetic autotrophs
What is a point where rate of photosynthesis is equal to cellular respiration?
Light compensation point
What factors affects photosynthesis?
- Water Availability
- Temperature
- Nutrient Availability
What is a catalyst for the fixing of carbon by RuBP?
RuBisCO
It is used by most plants and algae? (CO2 + Ribulose Bisphosphate = Phosphoglyceric Acid)
C3 Photosynthesis
It uses PEP carboxylase in the bundle sheath?
(PEP + CO2 = 4 carbon sugar)
*Prevents water loss
C4 Photosynthesis
It is limited to succulent plants in arid and semi-arid environments?
(takes place during night time)
*Prevents water loss
Crassulacean Acid Metabolism (CAM) Photosynthesis
What organism uses inorganic molecules (CO2) as energy source and important to sulfur and nitrogen cycle?
Chemosynthetic autotrophs
What organisms uses organic molecules as source of carbon and energy?
Heterotrophs
What organisms are plant-feeding?
Herbivore
What organisms are animal-feeding?
Carnivore
What organisms feed on non-living (detritus) organic matter?
Detrivore
What parasite full depends on it’s host for sustenance?
Holoparasites
What partially parasites it’s host?
Hemiparasite
What is the development of warning colorations for predators?
Aposematic Coloration
What is the development where noxious organisms develop aposematic qualities?
Mullerian Mimicry
What is the development where conspicuous qualities are mimicked by harmless organisms?
Batesian Mimicry
What are the 3 responses in selective predation pressure?
Type 1 - linear (/-)
Type 2 - linear at low density and increases slowly at intermediate food density (c)
Type 3 - feeding rate increases more slowly at low prey density (s)
What is the concept where the tangent maximizes profitability and determines optimal giving up time?
Optimal Foraging Theory
This is where the prey exhibits behaviour that can prevent detection or deter predators?
Ecology of Fear
This is where prey accounts for safe and risky area within it’s home range?
Landscape of Fear
