The correct answer is (c) elevation of a landmass above sea level.
What are the three primary ecosystem?
There are three broad categories of ecosystems based on their general environment: freshwater, marine, and terrestrial. Within these three categories are individual ecosystem types based on the environmental habitat and organisms present.
What is the key difference between a foundation species and a keystone species in a given ecosystem?
A foundation species is usually the most abundant, and a keystone species exerts the most influence on maintaining biodiversity. There is no difference the terms are used interchangeably. A foundation species is the least abundant, and a keystone species is the most abundant.
What is the key difference between a foundation species and a keystone species in a given ecosystem quizlet?
9. What is the key difference between a foundation species and a keystone species in a given ecosystem? A. A foundation species exerts the most influence on maintaining biodiversity while a keystone species is most abundant.
Which of the following biomes is characterized by abundant water resources?
There’s boreal forests, there’s the arctic tundra, there’s the chap rel um but if you were to look at the one that is characterized by the most abundant water resources, that would be tropical wet forests, also known as tropical rainforests there.
What is a biome in ecology?
A biome is an area classified according to the species that live in that location. Temperature range, soil type, and the amount of light and water are unique to a particular place and form the niches for specific species allowing scientists to define the biome.
Which of the following is not an abiotic factor?
The item in the question that is not an abiotic factor is the C. microbes in the soil. Since they are living things, they would be considered biotic…
Why are the following considered keystone species what impact do they have on the ecosystem?
A keystone species is an organism that helps define an entire ecosystem. Without its keystone species, the ecosystem would be dramatically different or cease to exist altogether. … The ecosystem would be forced to radically change, allowing new and possibly invasive species to populate the habitat.
How foundation and keystone species affects the structure of the community?
Foundation species change the environment where other species live, modifying it to benefit the organisms that live there. Keystone species maintain biodiversity; their removal can greatly alter the dynamics within the community.
Can species be both a foundation species and keystone species?
The key difference between keystone species and foundation species is that keystone species are the species that have a greater effect on all the other species in an ecosystem while foundation species are the species that play a major role in creating and maintaining a habitat for other species.
What is necessary in order for a species to be considered a foundation species?
What is necessary in order for a species to be considered a foundation species? The species must have a substantial influence on the community structure as a consequence of its high biomass.
What is a foundation species quizlet?
Foundation Species. Species that create/modify habitats and causing a positive effect on diversity, distribution, and abundance of other organisms (“set the stage”)
Which of the following correctly identifies the difference between a community and a population?
Population – All the members of one species that live in a defined area. Community – All the different species that live together in an area. Ecosystem – All the living and non-living components of an area.
Which type of biome is characterized by very little rainfall?
The correct response is desert. The desert environment is characterized by low rainfalls (less than 25 cm per year). They are one of the most dry biomes on the planet. The desert biome also has highly variable temperature swings, with high temperatures during the day and low temperatures at night.
Which of the following biomes is characterized by short growing seasons?
Though grasslands and deserts share some of these characteristics, the tundra is the only biome listed that is characterized by a short growing season, harsh winters, no trees, mostly migratory animal species, and less than 10in of rain per year.
How are terrestrial biomes determined?
Terrestrial biomes are distinguished primarily by their predominant vegetation, and are mainly determined by temperature and rainfall. Differences in temperature or precipitation determine the types of plants that grow in a given area (Figure 1). … Regions of similar climate and dominant plant types are called biomes.
