Succession, Biodiversity, and Finch Birds

The living organisms in an ecosystem such as plants and animals

• adaptation
• biotic
• decomposer
• abiotic

The non-living factors in an ecosystem such as rocks, water and temperature.

• natural selection
• biotic
• biodiversity
• abiotic

Organisms that make their own food. Also called autotrophs.

• Producer
• Parasite
• Scavenger
• Decomposer

An ecosystem that is not sustainable can break down when a natural disaster occurs. This can lead to organisms in the ecosystem either leaving the area or dying off.

Increased biodiversity results in a more sustainable ecosystem because —

• a greater number of plant species means that there is less barren land

• a greater variety of species present allows more organisms to adapt after changes occur

• the transition area between two ecosystems is narrower

• there are fewer species to be affected by environmental stresses

What keeps planets in the solar system from moving in straight lines through the galaxy?

• Light Energy

• Gravity

• Inertia

• Potential Energy

What energy transformations are occurring in this scenario? 

• electrical energy --> mechanical energy --> light energy 
• solar energy --> electrical energy --> light energy
  
• solar energy --> mechanical energy --> light energy 
• solar energy --> electrical energy --> mechanical energy 

The building up of an ecosystem after lava or glaciers have left nothing but rock.

• Secondary Succession
• Primary Succession 
• Natural Selection
• Adaptation

Rebuilding an ecosystem after a catastrophic event has occurred and soil is present.

• Primary Succession
• Secondary Succession
• Natural Selection
• Adaptations

The process where plants use the light from the sun to convert carbon dioxide and water into glucose. 

• Phototropism
• Chloroplast
• Photosynthesis
• Prokaryotic
