Random
True or False: Local species diversity is not directly related to the efficiency with which predators prevent the monopolization of the major environmental requirement by one species
False,
Local species diversity is directly related to the efficiency with which predators prevent the monopolization of the major environmental requirement by one species
True or False: Factors like seasonal variations in temperature and nutrient availability will influence the capacity of ecosystems to support higher-level carnivores
True
What is a food web?
An interconnected food chain of an ecosystem that shows what eats what
What is a keystone species?
An organism that helps define an entire ecosystem
True or False: Greater stability of production should be correlated with greater diversity, other things being equal
True
True or False: the animal diversity of a given system will probably be lower if the production is apportioned more uniformly throughout the year rather than occurring as a single bloom
False, the animal diversity of a given system will probably be higher if the production is apportioned more uniformly throughout the year rather than occurring as a single bloom
What are the components of a food web?
Producers , consumers, and decomposers
Give an example of a keystone species mentioned in the video
Sea otters, wolves, elephants, starfish, elephants, beavers, largemouth mass, etc.
When the top predator is artificially removed or naturally absent what happens to the system (according to the article)?
The system converges toward simplicity
In Less productive areas what happens to species of equivalent rank and what happens to diversity?
Less productive areas tended to have more species of equivalent rank and therefore greater diversity
What is a subweb?
groups of organisms capped by a carnivore and related in such a way that at higher levels there is little energy transfer to co-occurring subwebs
Explain what happens when a keystone species is removed.
the ecosystem would be dramatically different or in some cases cease to exist
According to the article, what is the single most important factor influencing the distribution or reproduction of marine invertebrates?
Temperature
When space-utilizing forms potentially dominate the shore what happens to diversity and how can it be prevented?
Diveristy is reduced and it can be prevented if a predator can prevent the space monopoly.
What are some factors that will influence the complexity of the food web?
Geographical factors, the scale of the food web, environmental stability
True or False (with explanation): A keystone species can be a herbivore or a carnivore
True, predators are often a common keystone species but can also be herbivores (ex. elephants). It just reliant on whether that species helps control the ecosystem
