Which statement best describes the relationship between snow geese and plants in the salt marshes that border the Hudson Bay?

Which statement best describes the relationship between snow geese and plants in the salt marshes that border the Hudson Bay? At low densities, the geese benefit the plants; at high densities, the geese harm the plants.

How do snowshoe hares change when predators are abundant?

Parasitism never results in the death of the organism, while predation and herbivory usually do cause the death of the organisms they eat. How do snowshoe hares change when predators are abundant? A. They evolve aposematic coloration.

Which of the following is most likely to prevent or stop an arms race between host and parasite?

Which of the following is most likely to prevent or stop an arms race between host and parasite? A trade-off between a host’s survival when parasitized and its reproductive success in the absence of parasitism.

What is the primary difference between interaction webs and food webs quizlet?

Interaction webs do not consider primary producers, whereas food webs do. Interaction webs include non-trophic interactions, whereas food webs do not. There is no difference between food webs and interaction webs. ? ?? Interaction webs include non-trophic interactions, whereas food webs do not.

What is the difference between a food web and an interaction web?

What is the primary difference between interaction webs and food webs? a. Interaction webs include more trophic levels. Interaction webs do not consider primary producers, whereas food webs do.

Which types of interactions are considered part of food webs?

Summary. Species interactions within ecological webs include four main types of two-way interactions: mutualism, commensalism, competition, and predation (which includes herbivory and parasitism). Because of the many linkages among species within a food web, changes to one species can have far-reaching effects.

At which stage of succession is facilitation usually the most significant factor?

early succession

Can humans cause primary succession?

Ecological succession is the somewhat predictable change in forest types over a period of time, usually decades. This succession is influenced by environmental factors such as soil type, water regimes, vegetation history, climate, and invasive species. Humans affect all of these factors.

What are the steps of primary and secondary succession?

Succession

  • In primary succession, newly exposed or newly formed rock is colonized by living things for the first time.
  • In secondary succession, an area that was previously occupied by living things is disturbed, then re-colonized following the disturbance.

What are examples of pioneer species in a primary succession?

The first organisms to appear in areas of primary succession are often mosses or lichens. These organisms are known as pioneer species because they are the first species present; pioneer species must be hardy and strong, just like human pioneers.

What are two similarities and two differences of primary and secondary succession?

Primary succession occurs following an opening of a pristine habitat, for example, a lava flow, an area left from retreated glacier, or abandoned strip mine. In contrast, secondary succession is a response to a disturbance, for example, forest fire, tsunami, flood, or an abandoned field.

What are two differences between primary and secondary succession?

The primary succession occurs following an opening of a pristine habitat, e.g., on lava flow, an area left from retreated glacier, or abandoned mine. The secondary succession is a response to a disturbance e.g., forest fire, tsunami, flood, etc.
