Asterionella formosa and Synedra ulna are species of diatoms that rely on silicate
(SiO2). At carrying capacity, A. formosa drives the abundance of silicate down to 1
μM, whereas S. ulna drives the abundance of silicate down to 0.4 μM.
Predict what will happen if Asterionella formosa and Synedra ulna attempt to
inhabitthe same space.
-Synedra ulna and Asterionella formosa will persist in sympatry, with A. formosa
below carrying capacity.
-Synedra ulna and Asterionella formosa will persist in sympatry, with S. ulna
below carrying capacity.

, -Synedra ulna will not persist because there is insufficient silicate left in the
environment by Asterionella formosa.
-Asterionella formosa will not persist because there is insufficient silicate left in
the environment by Synedra ulna.
-Asterionella formosa and Synedrra ulna will persist in sympatry, with both species
at carrying capacity. - Correct answer--Asterionella formosa will not persist
because there is insufficient silicate left in the environment by Synedra ulna.
Desert rodents and ants both depend on seeds from scrub plants as a food resource.
What conditions would favor the existence of both species within the biological
community?
-An increase in rodent predators in the biological community causes a dramatic
increase in the size of the ant population.
-Rodents and ants inhabit different areas of the habitat based on temperature and
rainfall patterns in the environment.
-Rodents prefer larger seeds as a food choice, while ants tend to consume smaller
seed types.
