A biologist studying alpine wildflowers notices that two populations of similar species are able to occupy the same niches. Howe
ver, species A is mostly found at lower altitudes, while species B is mostly found at higher altitudes. What has most likely caused the realized niches of these two wildflower populations to be smaller than their fundamental niches?
The answer is resource
partitioning. Due to competition between the two species population, the
two species evolved to utilize different resources. Therefore, this is rather than competitive exclusion that results to the out-competition
of one species, or competition that results in
a negative interaction between the species.
A fundamental niche represents the set of environmental conditions in which a species can survive and reproduce. A realized niche represents the environmental factors actually utilize by the species in order to survive after interaction with predatory and competing species. Here, the two species A and B are able to occupy the same niche that is they are able to live in fundamental nich but they acquire different locations for their survival that is lower and higher altitudes.
The species acquiring different habitat is their choice but there are some factors which are limiting their growth and abundance in the realized niches for example resources and predation.
Roots are built to absorb more and are placed right in their environment that they will be absorbing nutrients. Unlike leaves and stems, roots are not exposed to the daily elements in the outdoors and therefore don’t need the protection and filter that the waxy cuticle provides.
I believe this is the difference.. I hope this helps! :)
Forest fires burn away leaf and dead plant litter. It can also burn away invasive species or any diseased plants. Then, nutrients are returned to the soil which helps new plants sprout and thrive. Hope this helped !!
Explanation:They have round cells, called cocci (singular coccus), or rod-like forms (bacillus). Many Firmicutes produce endospores, which are resistant to desiccation and can survive extreme conditions.
