autotrophs utilize sunlight, which is the start of energy flow within a terrestrial ecosystem. As a result, consumers or heterotrophs are the organisms responsible for secondary production. The source of food of these organisms or herbivores is the producers and organisms that use herbivores as their food source. Aquatic and terrestrial ecosystems can be affected by a number of environment factors. The primary production capabilities of terrestrial ecosystems are affected by water, nutrients and temperature. Plants can die if they receive too much or too little water. The same situation will happen if they receive too much or too little temperature and light. The primary production capabilities of aquatic ecosystems are also affected by nutrients, light, and temperature. Fish can suffocate if water has too little oxygen. In order to ensure the survival of organisms, it is essential to maintain the balance of these factors. Therefore it is essential for ecologists to recognize the channel of trophic levels in order for them to effectively direct and handle ecosystems. It is also equally important to ensure that the habitats are maintained and handled properly.

"Before using Course Hero my grade was at 78%. By the end of the semester my grade was at 90%. I could not have done it without all the class material I found."

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
