Is the place or set of environmental conditions in which a particular organism lives?

A habitat is a place where an organism makes its home. A habitat meets all the environmental conditions an organism needs to survive.

What is primary production quizlet?

Primary production is the chemical energy generated by autotrophs during photosynthesis and chemosynthesis.

In which situation would primary succession occur quizlet?

Primary succession takes place in newly created habitats, such as newly formed islands. Primary succession occurs when the first species colonizes an area.

Which of the following is not generally true of K selected species compared to R selected species quizlet?

Which of the following is not generally true of k-selected species compared to r-selected species? They have shorter generation times. The most common reason that introduced species cause trouble is because they are larger than native species.

What is the primary productivity of an ecosystem?

primary productivity, in ecology, the rate at which energy is converted to organic substances by photosynthetic producers (photoautotrophs), which obtain energy and nutrients by harnessing sunlight, and chemosynthetic producers (chemoautotrophs), which obtain chemical energy through oxidation.

What is the proper definition for primary production?

Primary production is the production of chemical energy in organic compounds by living organisms. The main source of this energy is sunlight but a minute fraction of primary production is driven by lithotrophic organisms using the chemical energy of inorganic molecules.

Which best describes primary succession quizlet?

Primary succession occurs in an area with no life and no soil but secondary succession happens in an area where an existing community was disrupted. Which of the following best describes succession? The changes in species composition in a community over time as species colonize an area.

Which of the following is an example of primary succession quizlet?

Which of the following is an example of primary succession? Plant development on a layer of rock deposits.

What is primary succession quizlet?

primary succession. the series of changes that occur in an area where no ecosystem previously existed. pioneer species. the first species to populate an area; the are often lichens and mosses carried to the area by wind or water.

What is the basic unit of classification and a taxonomic rank of organisms that have common characteristics and can interbreed?

In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity.

What term is used to describe an organism which depends is subsistence on others?

heterotroph. noun. organism that cannot make its own nutrients and must rely on other organisms for food.

What is the role an organism plays within an ecosystem and the factors required to support that role?

In ecology, the term “niche” describes the role an organism plays in a community. A species’ niche encompasses both the physical and environmental conditions it requires (like temperature or terrain) and the interactions it has with other species (like predation or competition).

Which of the following is generally true of K strategist species compared to R-strategist species?

Which of the following is generally true of K-strategist species as compared to r-strategist species? They have longer life spans.

What are r-selected species?

r-selected species, also called r-strategist, species whose populations are governed by their biotic potential (maximum reproductive capacity, r). Such species make up one of the two generalized life-history strategies posited by American ecologist Robert MacArthur and American biologist Edward O.

In which situation would primary succession occur?

Primary succession occurs in essentially lifeless areas—regions in which the soil is incapable of sustaining life as a result of such factors as lava flows, newly formed sand dunes, or rocks left from a retreating glacier.

What is primary productivity measured in?

Primary productivity can be measured from the amount of oxygen consumed by a volume of water in a fixed period of time; water for which productivity is to be determined is enclosed in sealed white and dark bottles (bottle painted dark so light would not enter).

What is the primary productivity of an ecosystem quizlet?

” total amount of energy captured by photosynthesis”. Because the gross primary productivity of the ecosystem is a measure of the total amount of solar energy that the producers in the system capture via photosynthesis over a given amount of time.

What is primary productivity example?

Primary productivity is the process where inorganic substances are synthesized by organisms to produce simple organic materials. Primary producers, or autotrophs, are responsible for this phenomenon. Common examples of primary producers include diatoms, dinoflagellates, and coccolithophores.

What is the main product of primary production?

The main products of primary production are carbohydrates. How do scientists measure primary production? Scientist measure primary production by turning the amount of carbon into living things. The more carbons per square, the more productive the ecosystem is.

What are the two types of primary productivity?

  • Gross primary productivity, or GPP, is the rate at which solar energy is captured in sugar molecules during photosynthesis (energy captured per unit area per unit time).
  • Net primary productivity, or NPP, is gross primary productivity minus the rate of energy loss to metabolism and maintenance.

Which of the following is the best definition of primary succession?

What is primary succession? Primary succession is ecological succession that begins in essentially lifeless areas, such as regions in which there is no soil or where the soil is incapable of sustaining life (because of recent lava flows, newly formed sand dunes, or rocks left from a retreating glacier).

What is true of primary succession?

Primary succession occurs when new land is formed or bare rock is exposed, providing a habitat that can be colonized for the first time. For example, primary succession may take place following the eruption of volcanoes, such as those on the Big Island of Hawaii. As lava flows into the ocean, new rock is formed.

What is the main difference between primary and secondary succession quizlet?

What is the difference between primary and secondary succession? Primary succession is a process by which a community arises in a virtually lifeless area with no soil. Secondary succession follows a disturbance that destroys a community without destroying the soil.

Which factor is primary succession most likely to follow quizlet?

Primary succession would most likely occur after? A lava flow.

What is the definition of primary succession in biology?

Primary succession happens when a new patch of land is created or exposed for the first time. This can happen, for example, when lava cools and creates new rocks, or when a glacier retreats and exposes rocks without any soil. During primary succession, organisms must start from scratch.
