Answer: Mutualism
Explanation: Fungi have a lot of mutualistic relationships with other organisms. When we say mutualism, both organisms benefit from this relationship. A common example of a mutualistic relationship involving fungi is the mycorrhiza, a mycorrhiza is a mutualistic relationship between a fungus and a plant.
Nicotine on direct application in humans causes irritation and burning sensation in the mouth and throat, increased salivation, nausea, abdominal pain, vomiting and diarrhea. Predominant immediate effects consist of increase in pulse rate and blood pressure. Nicotine also causes an increase in plasma free fatty acids, hyperglycemia, and an increase in the level of catecholamines in the blood. There is reduced coronary blood flow but an increased skeletal muscle blood flow. The increased rate of respiration causes hypothermia, a hypercoagulable state, decreases skin temperature, and increases the blood viscosity.
For amphetamine the immediate effects are quicker reaction times, feelings of energy/wakefulness, excitement, increased attentiveness and concentration, feelings of euphoria. Side effects of amphetamines can include heart palpitations, dry mouth, headache, hostility, nausea, cognitive impairment, severe anxiety, lack of appetite, teeth grinding, dizziness, increased heart rate, heart palpitations, rapid breathing rate, hypertension (high blood pressure), increased body temperature, erectile dysfunction, irregular heartbeat.
Cocaine causes a short-lived, intense high that is immediately followed by the opposite intense depression, edginess and a craving for more of the drug the side effects are Loss of appetite increased heart rate, blood pressure, body temperature, contracted blood vessels increased rate of breathing, dilated pupils, disturbed sleep patterns, nausea, hyperstimulation, bizarre, erratic, sometimes violent behavior hallucinations, hyperexcitability, irritability, tactile hallucination that creates the illusion of bugs burrowing under the skin, intense euphoria, anxiety and paranoia, depression, intense drug craving, panic and psychosis, convulsions, seizures and sudden death from high doses (even one time)
The removal of the producers would cause the collapse of the entire food web. Primary consumers or herbivores, which feed on producers directly, would die off.
It depends on the type of interaction, but this typically wouldn't be an environmental scientist at all.
Explanation:
A primatologist, or a biological anthropologist, is most likely to study interactions among gorillas. Primatologists study primate behavior, ecology, intelligence, anatomy, and so forth.
A biologist or ecologist could also study gorillas and this wouldn't be unusual. They would likely study gorillas from a different perspective than a primatologist, who would be trained mainly in primates. A biologist would typically have a broader background that expands beyond primates.
Environmental scientists typically wouldn't study gorillas, although it's not impossible for someone to step outside of their field a bit.
Please note that these are all just generalizations. While most people studying gorillas come from a background in primatology, there are no steadfast rules determining who can study what.
