The first one is that transport proteins in the cell membrane ' Pick up ' molecules from outsides the cell and carry them in , while using energy in the process
The second method is that the the cell membrane surrounds a particle and takes it in
I hope that's help !
Answer:
An increase in the number of invasive species leads to a decrease in the diversity index. This species can alter the food web within an ecosystem by eliminating the local food sources leaving no food for the faunas. If plant diversity declines, the habitat would definitely lose its balance. The ecosystem would lose its balance. Plants are considered producers and are always the beginning of the food chain. Without plants, animals that consume plants will definitely decline it number; thus, also the consumers on top of the chain.
Explanation:
b.) The relationship is mutually beneficial.
c.) They share the same niche.
d.) One species benefits, while the other is neither helped nor harmed.
Answer:
C (they share the same niche)
Explanation:
Competition is a relationship between organisms resulting in a contest when both are trying to use the same resources related to their growth, reproduction and survivability. It is as a result of limited resources. Competition occurs in virtually all ecosystems in nature. This relationship develops when more than one organism in an environment has the same need for resources (niche) as another, to survive.
Each organism has a specific place in the ecosystem called NICHE. A species' niche is basically its ecological role or the function to which it is especially suited, which is defined by the set of conditions, resources and interactions it needs or can use.
The competitive exclusion principle says that two species can't coexist if they occupy exactly the same niche (competing for identical resources) or to put it in another way, two species in an ecosystem are bound to compete when they share the same niche (need for resources).
the answer is plate tectonics
Answer:
Option B, Marble
Explanation:
Limestone or marble is severely affected by the acid. Acid rain causes corrosion of all building and sculpture that are made up of marble. The sulphuric and nitric acid in the acid rain reacts with the calcite in the marble to dissolve it. This leads to peeling of marble structure which further exposes black crust made of gypsum formed by the reaction between calcite, water and sulphuric acid.
Answer:
Parasitism
Explanation:
Parasitism is the association between two organisms in which one organism (parasite) is benefited while the other (host) is harmed. The parasite is a heterotrophic organism that derives its nutrition from the living tissues of the host organism. In the given example, tick suck blood from their host and are exhibiting parasitism.
