Population Ecology
Difference between population size and density
What is size = total individuals; density = individuals per area
Shape of exponential growth curve
What is J-shaped
Definition of predation
What is one organism consumes another
Producers occupy which trophic level?
What is 1st
Zone where sunlight penetrates ocean water
What is the photic zone
Clumped dispersion is usually caused by what ecological factor?
What is resource availability
What limits population growth in the logistic model?
What is carrying capacity
Bright warning coloration is called
What is aposematic coloration
Biome with low rainfall and extreme temperature variation
What is desert
What is an estuary?
What is a mix of freshwater and saltwater
How does high population density typically affect birth rate?
What is decreases due to competition
Difference between intraspecific and interspecific competition
What is same species vs different species
Difference between Batesian and Müllerian mimicry
What is Batesian: harmless mimics harmful; Müllerian: both harmful
Why are tropical rainforests highly productive despite poor soil?
What is rapid nutrient cycling
Why does biodiversity decrease in deeper ocean zones?
What is less light and energy
Compare semelparity vs iteroparity
What is semelparity = reproduce once; iteroparity = multiple times
Give one density-dependent and one density-independent factor
What is density-dependent: disease; density-independent: weather
What does the competitive exclusion principle state?
What is two species cannot occupy the same niche indefinitely
Difference between species richness and abundance
What is richness = number of species; abundance = number of individuals
Difference between cosmopolitan and endemic species
What is cosmopolitan = widespread; endemic = restricted
Explain how energy budget influences reproductive strategy
What is tradeoff between offspring number and parental care
Why do K-selected species thrive near carrying capacity?
What is they are adapted to stable environments with competition
Explain how resource partitioning allows coexistence
What is species use different resources or niches to reduce competition
Why are foundation species critical to ecosystems?
What is they shape habitat and support other species
Explain spring vs fall turnover in lakes
What is mixing of water layers due to temperature changes
