How is asexual reproduction similar or different to plants versus organisms?
plants usually do it to grow and other organinsms to reproduce
Organisms belonging to the same can usually mate and prodice fertile offsprings?
Organisms of the same species can mate and produce offspring.
What is the types of organisms that are usually the pioneer species in primary succession?
Lichens
What Subdivisions withins a species are called?
Subspecies are the smaller groupings within a species. It is below the rank of species. Subspecies usually are interbreed and isolated organisms.
How is a biofilm different from a multicellular organism?
multicellular organisms are usually made up of specialised tissues that make up organs (a noteable exception is sponges). biofilms are made up of either a sinlge species or several species that fill niches in the biofilm ecosystem (one could liken the different species to different organs, providing different services to the biofilm as a whole).
What is biologicial species?
a group of organisms that can reproduce only among themselves and that are usually contained in a geographic region.
Some organisms usually reproduce asexually but resort to sexual reproduction to?
To carry on the species. When environment does not favor the organism it has to do so.

What is a infertile hybrid?
It is most common when two organisms of different species attempt to reproduce. The combination of genes is usually not fully functional meaning that the offspring is unable to reproduce itself. This can also occur in plants although to a lesser extent as plants are capable of polyploidy. In humans polyploidy causes complicated genetic diseases.

Why is it unusual that lichens are classified as species?
Because Lichen are actually a close symbiotic intertwining between two very different organisms - usually a fungi and an algae.

How can you determine if 2 organisms are in the same species?
If two organisms are able to mate and produce fertile offspring, then they are of the same species.Horses and donkeys are two different species because if they mate, they produce a mule which is sterile (not fertile). This shows horses and donkeys are of different species.
In what ways do some animals reproduce?
There are lots of ways that animals can reproduce. Some very simple organisms can simply divide. More complicated animals reproduce by getting a sperm and an egg together. Sperm and eggs are called gametes and have half the genetic material you need to make a new organism. Sperm is usually passed from a male to a female and this is called sexual reproduction but occasionally animals have both male and female organs and are called hermaphrodites. Hermaphrodites usually pass sperm to each other, although under some circumstances they can fertilise themselves.From animals kept in captivity we have discovered that some organisms like reptiles that are know to reproduce sexually, can occasionally lay fertilised eggs even though they have not had any contact with males of the same species. This may be an adaptation to enable a species to reproduce in the most difficult circumstances.
