Asexual reproduction is more productive. there are four ways to asexually reproduce: fission, budding, fragmentation and regeneration.
asexual reproduction can occur all over the year (eg bacteria multiplying). it is a major pro for endangered species and such where encountering a mate may be impossible. some organisms can reproduce both sexually and asexually.
the downside to asexual reproduction is that there isn't much variation in genetic codes so a disease could easily wipe out entire species.
such a problem doesn't exist with sexual reproduction. different genetic codes gives everybody their pros and cons. it follows Darwin's theory of Survival of the Fittest.
downsides of sexual reproduction is that it has certain time frames, making it less productive.
look at it a different way. if we humans were able to reproduce both sexually AND asexually this is what would happen:
every time we masturbate (which for some is a minimum of 5 times weekly) we would make new off spring, quickly over populating the world being so very productive.
but then women can only get pregnant once a month and it takes 9 months for the child to be born!!! it is obviously less productive.

Asexual reproduction is easier, less costly in energy, and is less likely to make a genetic mistake (mutation) in the reproduction of a new organism. Sexual reproduction is more energy costly, but it adds more genetic variation to the population because a new organism gets some traits from mom and some from dad.
In answer to your question, there is more production (and supposedly more success) among asexual organisms, but that is only because most asexually reproducing animals are amoeba-ish things and marine invertebrates that produce often and without much energy cost. However, if there were a disturbance or change in environment that reflected negatively on the population, and all the population were genetically identical, the population may all be wiped out. With sexual differentiation, there would be enough survivors with genetic differences and mutations for the population to survive (which introduces natural selection).
Hope that helps

Obviously, asexual reproduction has a production advantage but there are problems. First, when an animal reproduces without sex, the animal skips a step (of courtship and mating) and may be able to produce young the moment sexual maturity is achieved. Her young can then exploit what ever food source that their clone-mother has found. A good example of this is found in aphids.
The advantage for aphids (capable of both types of reproduction) is that the winged adult can land on a good food source with no predation and quickly produce an enormous colony of aphids.
The problem with asexual reproduction is that each of the young is a clone of their mother. The problem with identical biological units is that if one of the units is susceptible to a disease or has some other type of survival disadvantage, the entire clone-group has the same exact disadvantage and can quickly die out. Genetic diversity produces stability, but asexual reproduction exploits opportunism.

For a term paper you need a lot more than anybody on YA will tell you.
Asexual reproduction can be extremely prolific; look at how bacteria do it! and look at the starfish! Just chop it up and dump it in the ocean, and each piece is a new starfish.
Sexual reproduction has benefits in keeping the population healthy. It allows genetic mistakes to be dropped, and new diversity of traits to be developed.
