:The latitudinal gradient in species richness means that

שאלה #116627

		There is a general increase in species richness towards lower (tropical) latitudes
		There is a general decrease in species richness towards lower (tropical) latitudes
		There is no change in species richness between latitudes
		Different gradients in species richness exist without any clear trend

richness= increase , גם הביטוי חוזר על עצמו בשאלה ומופיע ב-2 אופנים חיובים , גדילה ועושר

שאלה #116631

		Losing a particular function due to reduced species richness can lead to adding other functions
		Losing a particular function due to reduced species richness can lead to loosing other functions
		Losing a particular function due to reduced species richness has no effect on other functions
		Losing a particular function due to reduced species richness has a positive effect on other functions

snowball - כדור שלג מוגדר כדבר רע , לכן התשובה תתחיל בלאבד loosing ותמשיך באותן אופן Loosing כמו כדור שלג מתגלגל

שאלה #116633

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

זה לא הגיוני כי לא יכול להיות מצב שאין שום השפעה תמיד תהיה השפעה בין אם חיובית או שלילית
