B15, 16 and 17 - Adaptations, Diversity, Organisation in Ecosytems Flashcards
All the topics meant for Ecology
Habitat
Place where an Organism lives
Population
All of Organisms of a species that in the same habitat
Community
Population of various species that live in together in the same habitat
Biotic Factors
Living Organisms/Factors of an environment: Amount of Food/Predators
Abiotic
Non Living Organisms/Factors: Soil PH, Moisture, Light or Wind Intensity
Ecosystem
Interaction of a community between Abiotic and Biotic Organisms
Competition (Animals)
- Competition is the fight against other Species of Animals to survive in the Ecosystem
- Animals need Food/Water, Territory and Mates (to reproduce) to live
Competition (Plants)
- Competition is the fight against other Species to survive
- Plants needs Light, Water/Minerals and Soil, all to Photosynthesise
Interdependence
- Abiotic/Biotic things relying on each other to live in an Ecosystem
- If one part of the Ecosystem falls, e.g. Organism dies out, then another part of the Ecosystem will be effected, e.g. Predators/Hunters have no more food
Types of Adaptations
Structural Adaptation - Physical Appearance
Functional Adaptation - Body Functions
Behavioural Adaptations - Effect Lifestyle/Behaviour, e.g. Nocturnal Creatures
Adaptations in Cold Climate
- Thick Fur, too keep warm
- Fatty contents, keeps warm and metabolic reactions can be used to produce water from the fat
- Camouflaged fur, for hunting
Adaptation in Hot Climate
- Fatty contents being a thermal insulator and produces water from metabolism
- Long eyelashes to keep dust out of their eyes
Plant Adaptations
- Cacti reduces water loss by not having many leaves
- Cacti have deep roots to gather as much rainfall as possible
- Plant would grow much taller to compete for light against other plants
- Large waxy leaves to gather as much rain
Extremophiles
- Organisms that live in extreme environments under high pressure and temperature
- Such as Bacteria located near Hydrothermal Vents
Producers
Plants that create their own energy through photosynthesis
