5 Questions
What reduces the sustainable number of larger animals at higher trophic levels?
Loss of energy through respiration and consumption
Why do phytoplankton require less energy for respiration compared to larger animals?
They have fewer bodily functions
What determines the seasonal plankton succession and bloom formation?
Abundant light and nutrients, low initial herbivore grazing pressure
Why is food and energy considered unidirectional as you move up trophic levels?
It takes more energy to maintain respiration and bodily functions at higher trophic levels
Where do phytoplankton activities primarily take place?
Photic zone where nutrients are not limited by too much light
