Natural disasters such as flooding and tornadoes are linked to ________________.

• primary
• secondary
• old field
• ecosystem

Which of the following best describes primary succession?

• Volcano wipes out ecosystem that gradually grows back from ash covered soil

• Volcano creates a new island of rock that must break down to form an ecosystem

• Forest fire burns down forest that must bounce back over time

• Tornado destroys a crop that must slowly grow back over time.

Which of these is NOT an example of interspecific competition?

• Oysters and barnacles competing for settling space on the rocky shore

• Goats and sheep in the same paddock competing for grass

• Ferns and kawakawa competing for shaded locations in a forest

• Stags competing for mates

The ecological role an organism performs in their specific environment is considered the organism's...

• Habitat

• Population

• Biome

• Niche

a relationship between two species in which both species compete for limited resources such that both species are negatively affected by the relationship

• Symbiosis

• interspecific competition

• species richness

• species-area effect

the differentiation of niches that enables similar species to coexist in a community

• character displacement

• climax community

• resource partitioning

• pioneer species
