The answer is cyanobacteria.
Bones: they lose calcium, becoming crispy
Muscle: they lose mass
Cartilage: becomes stiffer, but it does not make airway more rigid
D) connective tissue: It includes bone, blood, and lymph tissue, giving support to the skin and internal organs, becoming increasingly stiff when aging.
It should be connective tissue.
The ultimate source of energy (for most ecosystems) is "the sun"<span>. The ultimate fate of energy in ecosystems is for it to be lost as heat. Energy and nutrients are passed from organism to organism through the food chain as one organism eats another. Decomposers remove the last energy from the remains of organisms.

Therefore, The Answer is Option D.
Complete Question:
I made the grass diseased. This caused all of the populations above it (rabbit, snake, and hawk) to rapidly decrease over the 12 month period
(a) A major disturbance that the ecosystem was able to recover completely from __________
(b) A major disturbance that caused the ecosystem to stabilize at a new equilibrium ____________
(c) A major disturbance that caused the ecosystem to completely collapse __________
ANSWER:
(a) reducing the hawks to nearly zero
(b) removing all of the hawks
(c) removing all the diseased.
Explanation:
(a) reducing the hawks to nearly zero will cause low depletion of the producer (plants) and this will allow the plant to grow (without visible depletion) over a period of time.
(b) for the ecosystem to stabilize at a new equilibrium, the tertiary consumer (hawks) will be totally removed from the ecosystem. Since there's no tertiary consumer to checkmate the density of other components of the food chain, it will make it form a balanced ecosystem.
(c) for ecosystem to collapse, it's important to note that the removal of the producer (plants) will be bring about the loss of the ecosystem. Since, their is no manufacturer of food, the primary consumer (rabbit) in the food chain will be starved and overtime the rabbits will be wiped out and this will caused the loss of secondary and tertiary consumer in the long run.
