Final answer:
In a primitive community, we would expect to find pioneer species such as algae, and not complex animals like deer. The boreal forest biome is falsely described as being dominated by deciduous trees when it is, in fact, dominated by coniferous trees.
Step-by-step explanation:
The question regarding primitive communities seems to be focusing on ecological succession and the types of organisms one might find in the early stages of ecosystem development. A primitive community, such as the one formed after a volcanic eruption, would be initially colonized by pioneer species. Among the options provided, algae could be considered a potential pioneer species that can colonize bare rock or newly formed land. They do not require soil to grow and can engage in photosynthesis to produce their own food, which helps pave the way for subsequent colonization by other species.
As for the question on biomes, the false statement is c. Boreal forests are dominated by deciduous trees. Boreal forests, also known as taigas, are actually dominated by coniferous, not deciduous trees. Coniferous trees, such as pines, spruces, and firs, are able to survive the colder temperatures and acidic soil that characterize boreal forests.
Lastly, primitives such as a deer are not typically the first species to inhabit a newly formed ecosystem like that from volcanic lava. Deer are more complex organisms that would appear later in the ecological succession process, once the environment has been sufficiently established by pioneer species to support larger animals.
