Question

The following graphs look at the distribution of bumblebee communities based on several biotic and abiotic variables including: 1) Proboscis length diversity -diversity in the length of the bees' tongue, 2) Plant species richness-the number of plant species found at this location, 3) Phylogenetic diversity-the amount of bumblebee species diversity, and 4) "Degree-Days", which refers to the number of days above 0°C. For each axis representing diversity, a higher value means more diversity a) b) 10 20 30 40 50 60 Plant species richness 1000 1500 2000 2500 Based on the data seen in these two graphs, bees with long tongues were seen more often in what type of habitat? One with a smaller number of plant species. One that had had fewer than 1500 days above freezing One with relatively low amounts of species diversity One that had more than 1500 days above freezing One with high amounts of bumblebee species diversity One with a larger number of plant species

Explanation / Answer

Based on the data eenin these two graps, bees with long tongues were seen more often in one with a larger number of plant species

bumblebee speceis have different length of tongues to match the flowers they feed on.

This differrence in tongue lengths helps in reducing competition for food between different species as they are all not feeding on the same flowers.

Bumblebees with long tongues can reach the nectar in the long tubular flowers while medium and short tongues speceis collect nectar from smaller flowers.
