Answer:
The phylogenetic graph uses several types of variables to be formed, while other models use only one type of variable.
Explanation:
To create a phylogenetic chart, matrices with data on the studied species are used. These data are composed of morphological, chemical and / or genetic information that allow a detailed investigation about the ancestry of each species, in addition to allowing the correct grouping based on this ancestry and evolution.
A phylogenetic graph is different from other molecular models due to the number of data considered by it, since other models, such as the molecular clock, for example, only consider genetic based information.
The answer is D. Meadow animals that eat plants and plant products.
This is because the rabbits are primary consumers, which means they eat autotrophs. Other animals that eat plants like rabbits do would be on the same trophic level as them.
If a scientist wanted to compare the exact number of organisms at each trophic level within a desert ecosystem, the pyramid he or she would use would be the pyramid of numbers. The pyramid of numbers presents the population of organisms (individually) in each trophic level in a certain ecosystem.
