(18 cards)
What are alleles?
Alleles are different versions of a gene that determine specific traits or characteristics in an organism. They can be dominant or recessive, and individuals inherit two alleles for each gene, one from each parent.
What is biodiversity?
Biodiversity refers to the variety of living organisms in a particular ecosystem or on Earth as a whole. It includes diversity within species, between species, and of ecosystems.
What is climate change in environmental science?
Climate change refers to long-term shifts in temperature patterns, precipitation levels, wind patterns, and other aspects of Earth’s climate system. These changes are primarily caused by human activities, such as burning fossil fuels and deforestation.
What are cultural services?
Cultural services are the non-material benefits that ecosystems provide to humans, including recreational, aesthetic, and spiritual experiences.
What is ecological succession?
Ecological succession refers to the gradual process of change in species composition and community structure in an ecosystem over time.
What is ecological tolerance?
Ecological tolerance refers to an organism’s ability to withstand changes in its environment without suffering detrimental effects.
What are ecosystem services?
Ecosystem services refer to the benefits that humans receive from natural ecosystems, such as clean air, water purification, and pollination.
What are natural disruptions to ecosystems?
Natural disruptions refer to events or processes that occur in nature and can cause significant changes or disturbances within ecosystems.
What are phenotypes?
Phenotypes refer to the observable physical or biochemical characteristics of an organism, which are determined by its genotype and influenced by environmental factors.
What are provisioning services?
Provisioning services refer to the benefits that nature provides in terms of material goods or resources that are directly consumed or used by humans.
What are regulating services?
Regulating services are the ecological processes that help maintain balance in ecosystems and regulate important environmental factors.
What is resistance in ecology?
Resistance in ecology refers to how much an ecosystem resists change when faced with disturbances or stressors.
What is resilience in ecology?
Resilience refers to the ability of an ecosystem to withstand and recover from natural disruptions or disturbances.
What is secondary succession?
Secondary succession refers to the process of ecological succession that occurs in an area that has been previously disturbed or disrupted, but still retains its soil.
What is Shannon’s Index?
Shannon’s Index is a measure of biodiversity that takes into account both species richness and evenness within a community.
What is species evenness?
Species evenness refers to the relative abundance of different species within a community.
What is species richness?
Species richness refers to the number of different species present in a particular area or ecosystem.
What are supporting services?
Supporting services refer to the ecosystem functions that are necessary for the production of all other ecosystem services.
