The food webs an individual belongs; to list the food eaten today and trace the energy it contained back to its photosynthetic source; whether the individual is at same trophic level in all the food webs in which he participated; The ways that could change the biological role; whether that make food available for other people; why or why not.
Answer to Problem 1AL
Humans do not fall into the same trophic level it depends on the food habit of an individual. Some are carnivores and some are omnivores. As result, plants get a chance to recover.
Explanation of Solution
Food web is a graphical representation of what an organism eats and what eats that organisms, it is an interconnected chain. At the base, the plant is kept as they are the primary producers, at the second herbivores are placed that feeds on green plants, at the third carnivores are placed, that eat animals and at the fourth level omnivores are kept that eats both plants and animals.
Humans fall into the third and fourth trophic level. This is because the food habit of humans differs, some are animals or meat eater and some eat both plants and animals. Humans that eat deer or cow fall under the third level in the trophic but there are also humans, who eat salmons that fall under the fourth level.
The diet of today’s include- rice, chicken, and rajma. Rice and rajma are the autotrophs that can make their own food. Where else the chickens are carnivores that eat both plants and small insects.
No, we are not at the same trophic level because if individuals eat meat (carnivores) then that individual falls under third trophic level but if an individual eats both plants and animal (omnivores) than that individual will fall under the fourth level.
Yes, there may be a change in the ecological role that can make food more available like if all humans fall in the same trophic level there be less number of plants available. But as some individuals are carnivores as well as omnivores, it provides a chance to the plants to recover. As a result, there will be more numbers of the plants.

- At the large scale of the major ocean basins, do ocean currents tend to flow in a cyclonic or anti-cyclonic direction? How is this evidenced in the map of average sea-surface temperatures belowarrow_forwardThe map below shows sea-surface temperature (SST) anomalies during El Niño years. Please explain what is meant by “anomaly”. In El Niño years, which side (east or west) of the tropical Pacific Ocean experiences anomalously high precipitation totals and which side experiences anomalously low precipitation totals? Why?arrow_forwardWhen a body of cold air near earth’s surface moves into a region occupied by warmer air, the point of intersection is known as a cold front. What does this do to the vertical motion of the warm air and why? What does this do to surface pressure ahead of the cold front and why ?Does this tend to instigate cyclonic or anti-cyclonic atmospheric rotation ? Does this rotation tend to bring relatively warm air toward the poles or toward the lower latitudesarrow_forward
- As the atmosphere and ocean move, they are deflected due to the spin of the earth. Is the deflection to the right or to the left in the Northern Hemisphere? Is this the same in the Southern Hemisphere ? In both hemispheres, a low pressure will instigate cyclonic flow. In the Northern Hemisphere, does cyclonic flow circulate in a clockwise or counter-clockwise direction and whyarrow_forwardIs the seasonal cycle in temperature (temperature difference between warmest and coolest season) stronger in the tropics or high latitudes, and why ?How about in “maritime” areas that are regularly exposed to air that was recently over the ocean versus more continental areas, and why?arrow_forwardThe image shows the two different crusts on earth.

Philosophy and Fundamental concepts In this chapter, we discussed the five fundamental concepts of environmental geology: human population growth, sustainability, systems and change, hazardous Earth processes, and scientific knowledge and values. One interesting analogy for Earth is the Gaia hypothesis, which proposes that living organisms interact with their inorganic surroundings to form a synergistic, self-regulating system that helps maintain and sustain conditions for life on the planet. Now my question is Do you think the Earth is a living organism? Why or why not? I understand that many students use generative AI to assist with homework. While AI is undoubtedly a valuable tool for providing information, I believe that human judgment and analytical skills surpass what AI can achieve.
