When do species compete in an ecosystem?
Since food and other resources are limited, the members of a species must compete with each other to survive. Competition does not always involve direct physical fights between members of a species. Instead, competition is usually indirect.
Are organisms able to consciously direct the course of their own evolution?
No. Evolution is a consequence of selective pressure(s) from the environment acting on organisms. Virtually all living beings are not conscious of this process.The only species that *could* consciously direct its own evolution is Homo sapiens (humans), but currently it doesn't.Artificial selection can and has consciously directed evolution, but it always was a species acting over other different species, not on their own evolution.
What are some examples of direct evidence for evolution?
Polyploidy in plants, for one instance the doubling of chromosomes at mating, is direct evidence not only for evolution but for speciation as well. I fact many to most modern angiosperm species are developed this way.
How do interactions between organisms influence populations size?
Predators can affect population size through increased or decreased predation events. Direct and indirect competition between members of the same species can limit population size.
Why does natural selection not directly affect genes?
Natural selection acts on the way organisms interact with one another and with their environment. The genes of organisms are not usually themselves involved in this interaction: they direct it through intermediaries such as proteins. So natural selection must work through these intermediaries to affect genes.

What are the differences between direct manipulation interaction and command language interaction?
• Direct manipulation interfaces are usually easier to learn because they rely on recognition rather than recall. • The effect of operations tends to be easier to spot, and therefore, avoid in a direct manipulation interface because the consequences are normally visualized in such an interface. • Giving instructions tends to be more efficient than direct manipulation for experienced users.
