Exam 4 Learning Outcomes UPDATED
ACTUAL Questions and CORRECT
Answers
Ecology - CORRECT ANSWER - Study of interaction between living things and their
environment
Biome - CORRECT ANSWER - ecological community of plants, animals, and other
organisms that is adapted to a characteristics set of environmental conditions
Estuary - CORRECT ANSWER - Biomes where a source of fresh water, such as a river,
meets the ocean
Phenology - CORRECT ANSWER - The study of the effects of climate conditions on the
timing of periodic lifecycle events, such as flowering in plants or migration in birds
Keystone species - CORRECT ANSWER - Species that is instrumental in maintaining
diversity in an ecosystem
removing a keystone species from an ecological community may cause a collapse in diversity
Distinguish between climate and weather. - CORRECT ANSWER - -Climate refers to the
long-term, predictable atmospheric conditions of a specific area.
-weather refers to the conditions of the atmosphere during a short period of time.
Effects of greenhouse gases on Earth's climate. Why they have been increasing over the past
century. - CORRECT ANSWER - Help regulate earths temperature, but too many of them
cause the planet to heat up, leading is significant changes in climate
Human activities have cause an increase in gases, which is why we're seeing more extreme
weather and
environmental changes
, Interspecific interactions. - CORRECT ANSWER - The relationship between different
species
How climate change is influencing interspecific interactions. - CORRECT ANSWER -
Disrupting the timing, location, and strength of interactions between different species
can lead to competition, change in food availability, new predator-pray relationships, all affect
the survival and behavior of species in ecosystems
Trophic levels of zooxanthellae, coral, and starfish . - CORRECT ANSWER -
Zooxanthellae: 1st level (primary consumers) they make their own food using sunlight
Corals: 2nd level (primary consumers) feed on plankton but also get food from zooxanthellae
through mutualism
Starfish: 3rd level (secondary consumer) predators that may eat corals or other animals
Symbiotic relationships between zooxanthellae, coral, and starfish - CORRECT
ANSWER - Zooxanthellae and coral: mutualism both benefit from the relationship.
zooxanthellae helps coral grow and corals feed on plankton
Coral and starfish: predation or competition starfish may eat corals, harming them. disruption the
balance of the reef ecosystem
Threats to coral reef ecosystems. - CORRECT ANSWER - - Climate change: warming
waters, coral bleaching, ocean acidification
- Pollution: chemical pollution, nutrient runoff, plastics
- Overfishing: destructive fishing practices and overfishing of key species
- Coastal development: Habitat destruction and increased sedimentation
- Tourism: Physical damage and pollution from visitors.
- Invasive Species: Non-native species that harm coral reefs
- Natural Disasters: Hurricanes, cyclones, and disease outbreaks.
