Population Change

A change in the number of individuals of a specific species in an ecosystem.

Climate Change Impact

Changes in climate can cause species to move to different areas, affecting food sources and habitats.

Species Interdependence

Changes in the population of one species often affect the populations of other species in an ecosystem because they are part of the same food web or habitat.

Habitat Loss

The reduction or destruction of an area that provides living space for organisms.

Study Notes

Population Changes

  • Seabirds nest on cliffs and dive deep to eat small fish.
  • Small fish eat microorganisms which make their own food.
  • Microorganisms live in cold water.
  • If water warms, microorganisms move to cooler water, so do the fish that eat them.
  • Seabirds lose food if fish move, and may die or find new habitats.
  • Population change - alteration in the number of individuals in a population.
  • Climate change can affect species populations by changing their habitat.
  • Changes in one species' population can impact others in the ecosystem.

Habitat Loss

  • Habitats provide organisms with needs to survive.
  • Humans change habitats by building, roads, polluting water, or overfishing.
  • Human activity can affect the weather & temperature.
  • Habitat loss is a primary cause of extinction.
  • Coral reefs are diverse & valuable ecosystems.
  • Coral reefs support fish, other corals, and sea life.
  • Coral reefs are important for tourism & income.
  • Coral bleaching occurs when water temperatures rise.
  • Corals lose algae & turn white.
  • Bleaching stresses corals, often leading to death.
  • Healthy habitats are crucial for all organisms in a food web.
  • Loss of coral reefs can impact the entire ocean food web.

Plastic Pollution

  • Large amounts of plastic enter the marine environment.
  • Animals (fish, turtles, seabirds) mistake plastic for food.
  • Plastics aren't nutritious & can be harmful.
  • Plastic breaks down into smaller pieces (microplastics).
  • Coral filters seawater, also ingesting microplastics.
  • Increased plastic in the marine environment could harm marine life.
  • Actions to reduce plastic waste in the marine environment needed.
