Growth Curves, Energy Flow Test

Front

What is carrying capacity in an ecosystem?

Back

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

Front

What is the approximate carrying capacity of Paramecium caudatum cultured alone?

Back

150

Front

What is a producer in an ecosystem?

Back

A producer is an organism that can make its own food through the process of photosynthesis, converting light energy into chemical energy.

Front

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

Back

Exponential growth.

Front

How many predators does the squid have?

Back

3

Front

What does it mean when a population is below carrying capacity?

Back

It means that the population size is less than the maximum number of individuals that the environment can support, indicating potential for growth.

Front

What factors can affect the carrying capacity of an environment?

Back

Factors include availability of resources (food, water, shelter), environmental conditions, and interactions with other species (predation, competition).

Front

What is the difference between exponential growth and logistic growth?

Back

Exponential growth occurs when resources are unlimited, leading to a rapid increase in population size, while logistic growth occurs when resources are limited, leading to a stabilization of population size at carrying capacity.

Front

What is the significance of energy flow in an ecosystem?

Back

Energy flow is crucial as it determines how energy is transferred through food chains and food webs, affecting the structure and function of ecosystems.

Front

What role do decomposers play in an ecosystem?

Back

Decomposers break down dead organic matter, recycling nutrients back into the ecosystem and supporting the growth of producers.
