Two grizzly bears are fighting over a fish to feed themselves. what kind of interaction is this scenario, which works as a limiting factor in the bears’ survival?

The correct answer is- Intraspecific competition.

Intraspecific competition can be described as an interaction in a population where members belonging to the same species compete for a limited resource ( such as food, water).

As per the information given in the question, both organisms ( grizzly bears) belong to the same species and competing for fish, which is food for them.

Thus, it is an example of Intraspecific competition.

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
