Document Summary
Energy capture: functional responses, optimal foraging theory, marginal value theorem. Isat: saturation rate: lcp: light compensation point the point at which oxygen is being produced and consuming co2. Light availability and photosynthesis: some plants are better with variations of light availability. Photosynthetic response curves (fig 7. 20: grew plants in open environment (full light availability) and in shady regions. They are of the same species and are clones of each other: poplar plants in shade: different photosynthetic response curve, tend to maximize out lower, lower light compensation point. Functional responsible curves (7. 21: there are three different responses animals have to food availability, type 1 response: food availability on x-axis, food intake on the y-axis. This is a more common response: there is a linear trend (lots of prey). Overtime, the rate of prey intake declines to a maximum: this has to do with behaviour. At low food density, energy is spent looking for prey.
