Study Notes

Biotic and Abiotic Factors

Biotic Factors: Living components in an environment that influence the life of organisms, like predators and prey interactions.
Abiotic Factors: Nonliving elements affecting ecosystems, encompassing climate, geology, and atmospheric conditions.

Nutritional Roles in Ecosystems

Decomposers: Organisms that break down dead matter, facilitating nutrient cycling and energy flow in ecosystems; they are heterotrophic, relying on organic substrates.
Autotrophs: Organisms that produce their own food using inorganic substances and energy sources; examples include green plants, algae, and certain bacteria.
Omnivores: Animals that consume both plant and animal matter; they can be predators or scavengers depending on their feeding habits.
Herbivores: Organisms that exclusively eat plants; some feed on living plants while others break down dead plant matter.
Carnivores: Animals that primarily consume meat from live or dead sources, with some species considered carnivorous despite low meat intake.

Ecological Succession

Primary Succession: Occurs in lifeless areas with no soil, such as after lava flows or glacier retreats; initiates new ecosystems.
Secondary Succession: Follows disturbances in established ecosystems, like forest fires, allowing recovery and regeneration using preexisting soil.

Branches of Biology

Botany: Study of plant life; encompasses various sub-disciplines and is critical for understanding ecosystems; specialists in this field are called botanists.
Heterotrophs: Organisms that consume other living entities within a food chain, taking on roles of herbivores, carnivores, or omnivores.
