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.
Why do pollen grains only produce tube in flower of their own species?
because
Do organisms randomly mate with organisms that have a different phenotype or genotype?
Simple ones will try, but it is a waste of much energy. Thus behaviors were selected for to only mate efficiently. i.e. only with you own genotype.
What makes biology important?
Since we human beings are living organisms, we naturally have an interest in biology, the study of living organisms. Even aside from the relevance of biology to our own species, biology is relevant to many other species that form important parts of our lives, in terms of providing us with food, and many other things.
What type of organisms can use the engergy from the sun to make their own food?
Organisms that produce their own energy using sunlight are photosynthetic organisms. These are plants or other organisms that contain chloroplasts.
What are organisms that only mate with their own kind called?
A biological species I would think.
A bacterial species differs from a species of eukaryotic organisms in that a bacterial species?
Breeds with it's own species.

What example of competition between individuals within population and of competitions?
2 species of paramecium need to compete for their own resources!
Are plants are only organism in an ecosystem that can produce their own food?
Are plants the only organisms in an ecosystem that produce their own food? Ans:yes
What is a collection of organism whose members interact with one another?
The collections of interbreeding organisms are called species. Species are capable of reproducing on their own and is often known as largest organisms.
Do you accept the ethical position that each species has the inherent right to survive without human influence?
Each species have every right to survive, if not only humans do interfere with them through deforestation, destruction of their natural habitats, and also poaching them as food and selling them in black market or making them as a pet. This has to stop to prevent them from extinction.
Are plants the only organisms in ecosystem can produces their own food?
No
What is the competitve exclusion principal?
Simply put it is the principle that other organisms, sometimes of your own species, are excluded from your niche by competition for the same resources so organisms tend to different resources and then have their own niches were competition is lessened.
Are animals examples of photoautotrophs?
Only organisms that produce their own food
What is the importance of reproduction in animals?
Reproduction is an organism's way of creating a new generation of its species. Reproduction is essential for preserving a species (carrying on with the species), and replenishing the number of organisms in it to compensate for dead organisms. Without reproduction, a species would die out in one generation.
Do plants ever fight for anything?
Yes. They actively fight other species, and compete, to a lesser extent, with their own, for root space, water, sunlight, etc.
