Answer:
C) heat
Explanation:
An ecosystem comprised of biotic and abiotic factors interacting together, in a specified environment.
trophic levels of this ecosystem is the food chain or the level an organism is in the feeding level, this range from producer to tertiary consumer.
If we follow the pyramid of tropic level known as " Energy level" Heat is lost to the environment at each of the trophic levels of the ecosystem. The producer which has large area of the pyramid has a large energy, and as the primary consumer(second tropical level) which are herbivores feed on the producer(first tropical level)grass , it only takes just like 10% energy from the producer and the secondary consumer ( third tropical level) herbivores feed on primary consumer, and only get away with 10% of the energy and as the trend goes up the "Energy keep decreasing inform of heat" like that.

In arteriosclerosis, overproduction of abnormal collagen and decreased quantities of elastin lead to Decreased coronary artery perfusion.
Arteriosclerosis is a condition in which the arteries, which transport oxygen and nutrients from the heart to the rest of the body, thicken and stiffen, often limiting blood flow to the organs and tissues. Flexible and elastic arteries indicate good health. However, the artery walls can stiffen over time, a phenomenon known as arterial hardening.
The accumulation of lipids, cholesterol, and other chemicals in and on the artery walls is known as atherosclerosis. The accumulation is known as plaque. Atherosclerosis can constrict the arteries and obstruct blood flow. The plaque may rupture and cause a blood clot.
Symptoms of arteriosclerosis:
- chest pressure or discomfort (angina)
- sudden numbness or weakness in the arms or legs.
- speech slurs or speaking difficulties.
- vision briefly lost in one eye.
- weakened facial muscles
- ache while walking.
- elevated blood pressure
- renal failure
