Ecologists have come together for a meeting to determine the indirect and direct interactions between species that live in the h
abitat of a local pond. The feeding relationships were listed as: 1. Fish feed on larval dragonflies. 2. Adult dragonflies feed on bees. 3. Bees pollinate the terrestrial flowering plants.
1) Direct interaction: A direct interaction deals with the direct impact of one individual on another when not mediated or transmitted through a third individual
Direct interactions in the given habitat are:
Bee and dragonfly
Dragonfly and fish
Terrestrial flowering plant and bee
2) Indirect interaction: An indirect interaction is the impact of one organism or species on another that is mediated or transmitted by a third
The claim by the researcher is supported because of the known functions of insulin and growth factors. Both hormones have a tendency to respond to the presence of glucose. The growth hormone initiates STAT5 signaling for producing the Igf-1 factor that is important for utilizing glucose. The insulin hormone is well known for utilizing glucose.
