Answer:
<em>The correct option is A. X, because organism X has the same role as the grasshopper</em>
Explanation:
In a food chain or a food web, a primary producer can be described as an organism which feeds on producers. The producers, in this case, are the corn stalks. Grasshoppers are primary consumers in this food web because they feed on the corn stalks. X is also a primary producer, just like grasshopper, because it feeds on the corn stalks which are the producers. Hence, option A is correct.
Answer:
Yes, competition is likely to occur
Explanation:
Competition is an ecological interaction between organisms of the same or different species, resulting in the detriment of one of the organisms. Competition is generally caused when organisms in an ecosystem occupies the same niche i.e. they rely on the same ecological resource, which could be food, mate, space etc.
The case described in this question involving a Bagheera kiplingi (jumping spider) and acacia ants will likely result in competition because they both occupy the same habitat and feed on the same food (vegetable plant). The two organisms will have to compete for this limited resource, hence, it is regarded as an INTERSPECIFIC COMPETITION because it involves two different organisms.

Answer:
Nitrogen fixation
Explanation:
Biological nitrogen fixation is carried out by two types of microorganisms namely, symbiotic and free living microorganisms. Symbiotic microorganisms are bacteria f the genus <em>Rhizobium</em>. These are found in root nodules of leguminous plants. They convert atmospheric nitrogen into ammonia which is used directly by leguminous plants to form nitrogen containing organic compounds.
