Relationships - Habitats, Ecosystems, & Biomes
This biome receives very little rainfall and has drought-adapted plants.
What is a desert?
These growth patterns forms a J-shaped and S-shaped curve.
What is exponential and logistic growth?
Ozone in the stratosphere protects Earth from this harmful radiation.
What is ultraviolet radiation (UV)?
Breaking large habitats into smaller pieces.
What is habitat fragmentation?
If birth rate = 0.35, death rate = 0.20, what is the intrinsic growth rate (r)?
What is 0.15 (15%)?
This term describes the variety of life in an ecosystem.
What is biodiversity?
This term describes the maximum number of individuals an environment can support.
What is carrying capacity?
Melting glaciers contribute directly to this global issue.
What is sea level rise?
Give three negative human environmental impact.
Burning fossil fuels, industrial waste, and urbanization, causing habitat destruction, ocean acidification, and severe biodiversity loss.
The removal of a keystone predator results in exponential growth of herbivores and collapse of vegetation. This is an example of:
What is a trophic cascade?
If a grassland ecosystem experiences prolonged drought, this trophic level is likely to decline first.
What are primary consumers?
(due to decreased plant biomass)
If a population is below carrying capacity and resources are abundant, growth will most likely be:
What is rapid or exponential?
Is considered a pollutant primarily based on concentration exceeding natural levels and causing climate change.
Personal watercraft can negatively affect aquatic ecosystems by increasing this form of pollution.
What is noise pollution or water contamination?
When immigration exceeds emigration, the population will:
What is increase?
Removing this type of species can cause a trophic cascade in an ecosystem.
What is a keystone species?
(often a top predator)
In logistic growth, population growth rate is highest at this point on the curve.
(Graph Logistic growth curve)
What is at approximately half the carrying capacity?
Melting ice caps reduce the Earth's albedo (reflectivity), causing oceans to absorb more heat.
What is the relationship between ice cap melting and ocean surface temperatures?
If ecotourism is poorly managed, it can unintentionally reduce this key ecosystem quality.
What is ecosystem stability or biodiversity?
Greenhouse gases warm the atmosphere by absorbing and re-emitting this type of radiation.
What is infrared (IR) radiation?
Grow faster or reproduce more quickly than natives, outcompeting them for food, space, and sunlight, which reshapes the entire community structure.
Can alter soil nutrients, decomposition rates, and energy availability for lower trophic levels, affecting the entire food chain.
What are invasive species?
A population has 80 births, 40 deaths, 20 immigrate, and 10 emigrate. What is the net population change?
Net change = (B+I)-(D+E)
What is +50?
Adds fresh water, changing density and disrupting thermohaline circulation.
How's glacial melting affecting ocean currents?
If harvest rates exceed a population’s carrying capacity long-term, the likely result is:
What is population collapse?
Describe two positive effects of human activities on the environment, such as habitat restoration or species preservation efforts.
Habitat Restoration: Humans can restore damaged ecosystems to improve biodiversity and ecosystem health. Species Preservation Efforts: Humans can actively protect endangered species to prevent extinction.
