Plss I need help fastt 8. A food web is shown below.

a) Describe and explain two likely effects on this ecosystem if a virus attacked frogs, stopping their ability to reproduce. (4 points)

b) Consider a situation where scorpions are introduced into this ecosystem. These scorpions are predators of spiders, and there is no natural predator for these scorpions in the ecosystem. Describe two possible effects of introducing scorpions into this ecosystem. (2 points)

c) For simplicity, no detritivores are shown in this food web. Describe how detritivores would function in this ecosystem. (2 points)

sulfur dioxide

explanation: acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. these substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.

idk what the options are but

these is a strong electrostatic attraction between the ions hence a lot of energy is needed to overcome this attraction

this is why the boiling points are so high

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.

is it multiple choice?
