Transcript of Food Webs are teh greatest
The amount of light energy converted to chemical energy in a given time period by an ecosystem What is Predation? Herbivore - Plant Parasite - Host Predator - Prey Importance Effects What it is Types Importance Effects Types Predator - Prey Interactions Herbivore - Plant Interaction Parasite - Host Interaction Food Chain Overview One possible path that energy and nutrient may take as they move through the ecosystem Food Chain Overview Every organism needs to obtain energy in order to live The sequence to who eats whom in an ecosystem are:
-Primary Producer "Arms Race" Food Web Overview Food web consists of all the food chain in a single ecosystem Effects on predators Food Web Overview Predation Theory Cycle Canadian Lynx Immigration Energy is lost each time one organism eats another, so there have to be more plants than plant-eaters, more plant-eaters than meat-eaters Stabilization Food Web Overview Predator - Prey Interactions Herbivore - Plant Interactions Parasite - Host Interactions There's interdependence between organisms.
If one species goes extinct, it affects an entire chain of other species Evolution Example Types of parasites Examples Mind Blowing parasites Gross Primary Production- the total amount of light energy that is converted to chemical energy by photosynthesis per unit time
Net Primary Production- equal to to gross primary production minus the energy used for respiration by primary producers
NPP = GPP - R Primary Production Under Water (Marine and Freshwater Ecosystems) There are two main limiting factors for primary production in aquatic ecosystems, light and nutrients. Light Limitation Light is needed for photosynthesis and so is very important for primary production. In an aquatic ecosystem, light has to go through the water before it can get to the plants. Nutrient Limitation Nutrients are the main limiting factor of primary production in aquatic ecosystems. A limiting nutrient is an element that must be added in order to increase production. ROCKS! Alive Lithops History Location Classification Location History Classification TY Eutrophication When there are large amounts of nutrients added to lakes which promote a large growth of cyanobacteria, or algae, this eventually leads to the death of almost all of the fish species.
