An interaction network. A predator/prey cycle. O Coevolution. An obligate mutualism.
- Which of the following statements most accurately describes the example of species interactions for ants, plants and aphids Question 2 options: The burdock plant is negatively affected by a heavy aphid investation, the ants are negatively affected by the aphids and aphids are positively affected by the ants. The burdock plant is negatively affected by a heavy aphid investation, the ants are positively affected by the aphids and aphids are not affected by the ants The burdock plant is negatively affected by a heavy aphid investation, the ants are positively affected by the aphids and aphids are positively affected by the ants. The burdock plant is not affected by a heavy aphid investation, the ants are positively affected by the aphids and aphids are positively affected by the ants.What role does sexual selection andmale competition play in the evolution of aspecies?Mutualism often involves co-evolution of mutualists. Describe taking the example of animal plant (wasp-fig) relationship.
- Ants form associations with many types of other insects that feed on the sap of plants.One of these types of insects is an Ecuadorian tree hopper. You think that theassociation between the ants and treehoppers might be a mutualism. Tree hoppersfeed on plants, and the ants feed on the “honeydew” that is excreted as waste by thetreehoppers. In return, the ants may protect the treehoppers from predators les and controls should follow from your methods.QUESTIONS1.

Identify one control treatment in the experiment, and state if it is a positive…Describe how coevolution, as with the hummingbird bill and hummingbird-pollinated flowers, is different from the kind of evolutionEuropean honeybees as their name suggests originated in Europe but have now spread to all continents except Antarctica. They pose an added threat to many native bee species already at risk of declining numbers or even extinction due to increasing urbanization. A research conducted in Australia has very recently published in the Biological Journal of the Linnean Society. According to the study, a competition between the native bees and the introduced European honeybee is particularly intense in residential gardens dominated by non-native flowers (the native bees have co- evolved to forage on) and occurred when the bees shared the same flower preferences. European honeybees, being very abundant, and effective foragers, with the ability to exploit a wide range of flowers, can outcompete native bees for nectar and pollen resources. In this condition, what would you suggest rescuing the native bees as a biotechnologist? Justify your reasoning.
- Which of the following statements is true about the plant-bird seed dispersal mutualisms in Hawaii? For the plants the mutualism is obligate, but for the birds it is a facultative relationship Most of the seed dispersal is performed by non-native bird species All options are true The native bird species that act as seed dispersers have gone extinct. SCIENTIFIC INQUIRY You are testing the hypothesis thatincreased population density of a particular plant speciesincreases the rate at which a pathogenic fungus infectsthe plant. Because the fungus causes visible scars on theleaves, you can easily determine whether a plant is infected.Design an experiment to test your hypothesis. Describe yourexperimental and control groups, how you would collect data,and what results you would see if your hypothesis is correct.Use the word bank for the best answer to fill in the blank: Navigational, transportation, nutritional, facultative, obligate, very fun, antagonistic, co-evolution, symbiosis, predatory, beta, alpha. In this mutualistic interaction between theses two organisms, the plant is benefiting from a mutualism and the fly is benefiting from a mutualism. The flower is pollinated by many different insect species making this a mutualism for the plant.
