Which is a weakness of traditional food webs when they are applied to complex ecological problems?
question 12 options:

a food web does not represent all the links in an actual ecosystem.

food webs do not account for non-native species in the environment.

the many food chains of a food web make it too complicated to use.

trophic levels are not taken into account when creating a food web.

The correct option is A. A food web does not represent all the links in an actual ecosystem.

Explanation:

A food web can be described as a combination of different food chains. Although a food web reflects the energy flow of an area, it doesn't illustrate the actual links in an ecosystem. For example, it is not possible to know how much energy is being transferred in a food web. The role of abiotic factors in an ecological problem can also not be determined by a food web. A food web will also not give the information of the number of organisms present.

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
