Chapter 38, Problem 1WIO
Summary Introduction
To determine:
The conclusions about the competition between the two species of paramecia and their relationship.
Concept introduction:
In this two species of paramecia are used when they are grown separately, each population was proportional to the amount of food but when both are grown on the same dish only one species survived.

Students have asked these similar questions
Which statement about the classic competition experiments involving two
Paramecium species is FALSE?
The experiment involved interspecific competition.
The experiment involved exploitation competition.
Each species, when grown alone, exhibited logistic growth.
When grown together, the species exhibited logistic growth, but each reached a
lower carrying capacity than when it was grown alone.
What are some conditions that might lead to a mutualistic organism becoming a predator/parasite. Select all that apply.
A. Mutualistic nitrogen fixation bacteria might reduce the competitive ability of their host plants in environments with high N availability, because of the energetic costs to the plants of supporting the bacteria
B. none of the above
C. Mutualistic nitrogen fixing bacteria can become parasites in soil with low nitrogen availability because of the energy costs to the plant of supporting the bacteria
D. A mutualist fish species that feeds on ectoparasites of another fish species, might switch to feeding/removing important host tissue or secretions when ectoparasite abundance is too low.
Use the following information to answer the next
question.
When intraspecific competition occurs within a
species, some individuals may have a competitive
advantage over others. For example, some members
of a plant species may be able to grow longer roots
and absorb more water. These individuals have an
advantage over other members of the species
during periods of drought, and are able to survive
to pass this competitive trait to their offspring.
From the information given above, one can
conclude that intraspecific competition promotes
O inbreeding
O natural selection
O artificial selection
speciation

- You are trying to develop a new anti-termite chemical that will not harm environmentally beneficial insects. Because termites are adapted to eat only wood, they will starve if they cannot digest this food source. Termites have two symbiotic partners: the protozoan Trichonympha collaris and the bacteria it harbors that actually produce the enzyme that digests the wood. Knowing this, how might you prevent termite infestations without targeting the termites directly?arrow_forwardSuppose that researchers wanted to examine the combined effects of an introduced predator (a trout) and the trematode parasite Ribeiroia on amphibian populations. To do this, they established frog populations in each of 40 artificial ponds. Each pond was assigned at random to one of four treatments (10 ponds per treatment): 1) neither trout or parasites were added to the pond (the "No trout, no parasite" treatment); 2) no trout were added but parasites were added ("No trout, parasite added"); 3) trout were added but parasites were not added ("Trout added, no parasite"); and 4) both trout and parasites were added ("Trout added, parasite added"). Each pond contained refugia where tadpoles could avoid attack by trout, to avoid fish predators driving frog populations to extinction in an artificial pond, unlike what typically occurs in a natural pond. After two breeding seasons, the researchers estimated the density of frogs in each pond. The results are shown in the table and the figure.…arrow_forwardUse the graphs to answer the question below.

A. Yucca plants are pollinated only by moths of the genus Tegeticula; however, some of the moth species 'cheat" by laying eggs on seeds without pollinating the plant. B. Large-sized lice of the genus Columbicola tended to live on larger species of pigeons. Body size matching had a significant effect on the ability of lice to escape defensive preening by the host bird. C. The nonvenomous yellow-eyed salamander has the same coloration as the toxic California newt. Related nontoxic salamanders which do not mimic the newts are prone to attacks by predators. D. Glochidion trees and Epicephala moths are in an obligate mutualism with each other. Significant cospeciation led to an increase in diversity of the two species.arrow_forward
