Interspecific competition - Study guides, Class notes & Summaries

APES Semester 1 Exam (Unit 1, 2, 3, 4) | questions and answers 2. Circle the letter next to following statements regarding species interdependence if it is true? a. As association of two species where one benefits and the other is unaffected is called mutualism. b. An interspecific competition where both partners derive benefits from each other is called commensalism. c. A relationship between two species of organisms where both partners are benefitted from each other is called mutualism. ...

The study of how organisms interact with one another and with their nonliving environment is - ecology In a deciduous oak forest in the northeastern United States, one example of a nonliving component of the ecosystem is - sunlight that filters through the canopy A population grows exponentially when - the birth rate exceeds the death rate and immigration exceeds emigration. The different species within an ecosystem that interact in various ways make up a(n) - community All members o...

APES Unit 1 Exam Review (2023/2024) Graded A+ intraspecific competition between members of the same species interspecific competition between members of different species competitive exclusion 1 species is a stronger competitor than the other coexisting species species alter behaviors to minimize competition, altering their niche niche A species role in an ecosystem selective pressure when the environment pushes an individual or population to adapt or evolve parasitism One organism benefit...

the current interglacial is warmer or colder than 125000 years ago - warmer living on or over the shelf - neritic living past the shelf - oceanic living off the bottom - pelagic living on the bottom - benthic neritic exposed to air - intertidal neritic not exposed to air - subtidal The study of interactions between organisms and their environment - ecology characteristics of ecosystems - structure and function structure (composition) - biotic and abiotic components, conditions function...

what is a biological community? - Answer All of the populations of organisms living and interacting in a particular area commensalism - Answer interaction where one species benefits and the other is unaffected competition - Answer interaction where individuals use the same resources, lowering fitness for both -/- consumption - Answer interaction where one organism eats or absorbs nutrients from the other, +/- mutualism - Answer interaction where two species benefit +/+ three key t...

90% of the worlds population growth in the next century is expected to occur in - less developed countries a biological communitys productivity is a measure of - the amount of biomass produced in the community a keystone species is a species whose presence - influences the population size of many other species in its community a tritmouse and a chickadee are living in the same territory and are using some of the same resources. The best way to classify this interaction is - interspecific ...

What are the four main factors that determine distribution & abundance of species - selection - intra and interspecific interactions - drift - Dispersal -- movement within and between systems - Speciation/history Compare deterministic and stochastic effects - Deterministic -- lead to non-random, predictable patterns over time - Stochastic -- Random chance What is a niche? What is larger - fundamental or realized? - Niche -- Range of resources that the species is able to use or the range of con...

Eco-centric - Correct Answer Excludes humans Anthropocentric view - Correct Answer Humans are there to preserve nature Gaia - Correct Answer It compares the Earths to a living organism in which feedback mechanisms maintain equilibrium. Abiotic factor - Correct Answer A non-ling, physical factor that may influence an organism or ecosystem; i.e. the temperature, sunlight, pH, salinity, precipitation Biotic factor - Correct Answer A living, biological factor that may influence an organi...
