Mutualism occurs when organisms need protection (e.g., "guest defenders" or "guest cleaners"), when immobile organisms need to reproduce (e.g., pollinators or seed dispersers), and when organisms need to expand tolerances.

What kind of organisms need estuaries for nurseries?

Estuaries are important nurseries for many species of fish, crustaceans, and shellfish. These organisms rely on the shallow, nutrient-rich waters of estuaries for protection from predators, access to food, and optimal conditions for growth and development before moving to deeper waters as adults.


What adaptations do organisms of grasslands have that organisms of forest do not need to have?

Most organisms, such as gophers and ground squirrels, need to burrow underground to keep safe from predators like coyotes, hawks, owls and foxes. Such animals do not need to burrow beneath the soil surface in forests because the deciduous growth of shrubs provides the necessary cover to keep them hiding.


Why do humans need a skeletal system but not an amoeba?

Humans need a skeletal system to provide structure, support, and protection for their body. Amoebas, being single-celled organisms, rely on their flexible cell membrane to maintain their shape and do not require a skeletal system.


What type of organisms have an exoskeleton?

Organisms such as insects, crustaceans (e.g. crabs, lobsters), and arachnids (e.g. spiders, scorpions) have an exoskeleton. This external skeleton provides support and protection for their bodies.


Do all organisms need air to survive?

All living organisms need water to survive, because they have cells. With air, not all living organisms need air. Some forms of bacteria do not need oxygen to live, and others can't stand oxygen.
