What is the role of chloroplasts in plants?

Back

Chloroplasts are organelles in plant cells where photosynthesis takes place, converting light energy into chemical energy.

Front

Define competition in ecology.

Back

Competition is a relationship that occurs when two or more organisms of the same species need the same resource at the same time.

Front

What type of growth model is characterized by a rapid increase in population size?

Back

Exponential growth model.

Front

What is an independent variable in an experiment?

Back

The independent variable is the variable that is changed or manipulated to observe its effect on the dependent variable.

Front

What is a food web?

Back

A food web is an illustration that uses arrows to show the many possible directions in which matter and energy can pass through organisms in an ecosystem.

Front

What is the difference between a food chain and a food web?

Back

A food chain shows a linear sequence of energy transfer between organisms, while a food web illustrates the complex interconnections between multiple food chains.

Front

What is the significance of the energy pyramid in an ecosystem?

Back

The energy pyramid illustrates the energy flow and loss at each trophic level in an ecosystem, showing that energy decreases as it moves up the pyramid.

Front

Define symbiosis.

Back

Symbiosis is a close and long-term interaction between two different species, which can be beneficial, harmful, or neutral.

Front

What is logistic growth?

Back

Logistic growth is a model of population growth that shows how a population grows rapidly at first and then levels off as it reaches carrying capacity.

Front

What is the carrying capacity of an ecosystem?

Back

Carrying capacity is the maximum number of individuals of a species that an environment can sustainably support.
