Which of the sentences below is incorrect:

1

שאלה #15288

		Species extinction may cause a reduction in the functionality of an ecosystem
		Healthy ecosystems can buffer against local extinctions to maintain local stability
		Degraded ecosystem has no effect on the extinction probability of the remaining species
		Habitat loss in an already degraded ecosystem may lead to local instability

Most species in the world are?

1

שאלה #15289

Usually, smaller species have:

1

שאלה #15290

		More restricted ecological requirements
		Less restricted ecological requirements
		Similar ecological requirements as larger species
		Wide ecological requirements

In the species-area relationship curve, the 'z' parameter reflects:

1

שאלה #15291

		The intercept of the line with the Y axis
		The intercept of the line with the x axis
		The slope of the line on a logarithmic scale
		The decrease of species richness with area

Larger areas, usually:

1

שאלה #15292
