Answer:
Negative feedback.
Explanation:
It is negative feedback because the reactions triggered by low glucose levels are trying to rebalance the glucose concentrations in our body to make it work properly.
In positive feedback, a product will only stimulate more the components that lead to that product to produce more of it, increasing the product's effect and an imbalance.
In ecology, a disturbance is a temporary change in environmental conditions that causes a pronounced change in an ecosystem.
Disturbances often act quickly and with great effect, to alter the physical structure or arrangement of biotic and abiotic elements.
Disturbance can also occur over a long period of time and can impact the biodiversity within an ecosystem.
Major ecological disturbances may include fires, flooding, storms, insect outbreaks and trampling.
Earthquakes, various types of volcanic eruptions, tsunami, firestorms, impact events, climate change, and the devastating effects of human impact on the environment (anthropogenic disturbances) such as clearcutting, forest clearing and the introduction of invasive species can be considered major disturbances.
Not only invasive species can have a profound effect on an ecosystem, but also naturally occurring species can cause disturbance by their behavior.
Disturbance forces can have profound immediate effects on ecosystems and can, accordingly, greatly alter the natural community. Because of these and the impacts on populations, disturbance determines the future shifts in dominance, various species successively becoming dominant as their life history characteristics, and associated life-forms, are exhibited over time.
I think the absence of light will will stop the leaves from photosynthesis because light is necessary to make plant food.

Humans have bigger pelvic bones than four legged animals because animals and humans share more than 70% of our DNA with animals so as the animals get smaller, our bones become bigger.
2100 x .45= 945 calories
945 calories divided by 4 calories/g = 236.25 grams
