Seeds Ans: Renewable resources
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. Ans: -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?
