Ecosystems & Biomes

The living and non-living things in an environment EX: a neighborhood

• the sun 2. earth’s core

Opposite of cellular respiration Anabolic (small molecules combined) Energonic (stores energy) Only in producers

Opposite of photosynthesis Catabolic (molecules broken) Exergonic (releases energy) For plants & animals

Trap energy from sunlight and use it to synthesis starch / glucose in process called photosynthesis Producers

Used by “special producers” Get energy from earth’s core Make food via chemical reactions EX: extremophiles

Heterotrophs must obtain nutrients from plants & other animals

Only eats plants EX: cows, rabbits

Only eat meat EX: snakes, lions, owls

Eat both plants and animals EX: humans, bears

Eats scraps, do not hunt EX: gulls, vulture

Breaks down decaying plant / animal material through chemical EX: bacteria, fungus

An animal that is hunted by another for food EX: salmon Key feauture is eyes on side of their face to watch their environment

Organism that primarily obtains food by killing & consuming other organisms EX: grizzly bears Key feature is front facing eyes to narrow in on prey

Living organisms interact with their inorganic surrundings on Earth to form a self-regulating complex system that helps to maintain and perpetuate the conditions for life on the planet - life maintains conditions suitable for its own survival

Position that organism occupies in food chain / position group of organisms in community occupy in food chains

Producer

Herbivore primary consumers

Carnivore / Omnivore secondary consumer

Carnivore tertiary consumer

Chain that is interconnected with other organisms

Relationship of the mass (amount) of organisms

Records number of individuals at each trophic level

Shows flow of energy throughout each trophic level First layer (autotrophs) have the most energy Only 10% of energy in one trophic level is transferred to the next due to loss in heat & metabolism
