Question

when a crocodile eats a fish, the interspec could be expressed as ____ for the crocodile and ____ for the the sum total of a populations use of the biotic and abiotic resources of its 1 point habitat constitutes its environment evolution ecological niche which of the following is an example of predation? 1 point a lizards camouflage a hawk swooping down quickly to capture, kill, and eat a prairie king snake a goldfinch feeding on the seeds of a thistle plant in an ecosystem, you would expect to find interspecific competition between * 1 point males and females of a species in which both sexes occupy the same niche. populations of two species that occupy the same niche. a prey species and its predator

Explanation:

• First question: In a predator - prey relationship (crocodile eating fish), the predator (+) benefits as it gets food, and the prey (-) is harmed. So the interaction is expressed as + - (plus, minus).
• Second question: The ecological niche is defined as the sum total of a population's use of the biotic and abiotic resources of its habitat.
• Third question: Predation is when one organism (predator) captures, kills, and eats another (prey). A hawk swooping down quickly to capture, kill, and eat a prairie king snake is an example of predation. A lizard's camouflage is a defense mechanism, and a goldfinch feeding on thistle seeds is herbivory (a type of consumer - resource interaction but not predation in the classic animal - on - animal sense).
• Fourth question: Interspecific competition occurs between populations of two species that occupy the same niche as they compete for the same resources. Intraspecific competition (between males and females of a species) is a different type of competition, and a prey - predator relationship is not competition.

Answer:

• First question: + - (plus, minus)
• Second question: ecological niche
• Third question: a hawk swooping down quickly to capture, kill, and eat a prairie king snake
• Fourth question: populations of two species that occupy the same niche
