Ecosystems (Form and function)
- Adaptation to environment
- Habitat: where an organism lives
- Geographical location
- Physical location
- Ecosystem type
- Adaptations to abiotic conditions
- Marram grass: rolled leaves
- Marram grass: deep rhizomes
- Red mangrove: stilt roots
- Red mangrove: salt exclusion
- Range of tolerance
- Optimum range
- Zones of stress
- Zones of intolerance
- Transect and sensors
- Coral reef conditions
- Shallow, clear water
- Warm temperature
- Normal salinity
- Slightly alkaline pH
- Biomes: temperature and rainfall
- One ecosystem type develops
- Convergent evolution
- Six named biomes
- Desert and rainforest species
- Saguaro: CAM, water storage
- Camel: conserves water
- Kapok: buttress roots
- Drip-tip leaves
- Habitat: where an organism lives
- Ecological niches
- Niche: role in ecosystem
- Biotic interactions
- Abiotic interactions
- How food is obtained
- Oxygen tolerance
- Obligate anaerobe
- Facultative anaerobe
- Obligate aerobe
- Modes of nutrition
- Photosynthesis: autotrophs
- Holozoic: all animals
- Saprotrophic: decomposers
- Mixotrophic: Euglena
- Archaea: varied energy sources
- Light
- Inorganic chemical oxidation
- Carbon compound oxidation
- Hominid dentition and diet
- Homo sapiens: omnivore
- H. floresiensis: omnivore
- Paranthropus robustus: herbivore
- Herbivory and predation
- Insect mouthparts
- Thorns and toxins
- Detoxifying herbivores
- Chemical, physical, behavioural
- Harvesting light in forests
- Canopy trees
- Lianas
- Epiphytes and stranglers
- Shade-tolerant shrubs, herbs
- Fundamental and realized niches
- Competitive exclusion
- Elimination or restriction
- Each niche unique
- Niche: role in ecosystem
