Flashcards : Ecosystem Energy and Matter Dynamics — 24 cartes

Interconnected feeding relationships in ecosystems.

Transferred from producers to consumers, decreasing at each level.

Toxins build up in top predators through bioaccumulation.

Aquatic ecosystem with algae, insects, fish, birds.

Matter made of tiny particles in constant motion.

Solids vibrate, liquids slide, gases move freely.

Reactions with oxygen releasing heat and light.

Carbon dioxide and water.

Carbon monoxide, soot, pollutants.

Conduction, convection, radiation.

Chemical to thermal energy in combustion.

Visualize energy flow and losses.

6CO₂ + 6H₂O + light → C₆H₁₂O₆ + 6O₂.

C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy.

Main energy currency in cells.

An object stays at rest or moves uniformly unless acted upon.

Force equals mass times acceleration (F=ma).

Every action has an equal and opposite reaction.

Solar, wind, fossil fuels, hydro.

Greenhouse gases from burning fossil fuels.

Pollution, habitat loss, greenhouse effect.

Stored energy due to position, e.g., at height.

KE = ½ mv².

Reactions that absorb heat from surroundings.
