5th Grade:Alabama Science Assessment Review

Content Standard 9:

Describe the relationship of populations within a habitat to various communities and ecosystems.


Eligible Content:

  • Describe the relationships between consumers, producers, plant eaters, meat eaters, and plant and meat eaters.

  • Describe the relationships associated with population, community, and ecosystem hierarchies.

  • Know the terms biotic, abiotic, mutualism, commensalism, and symbiosis.

  • The Rumen - this is the largest part and holds up to 50 gallons of partially digested food. This is where the 'cud' comes from. Good bacteria in the Rumen helps soften and digest the cows food and provides protein for the cow.

An example of a mutualistic relationship in which both animals, the remora and the shark, work together.

The sea anemone and clown fish is an example of mutualism.

Mutualism is any relationship between two species of organisms that benefits both species. This is the relationship most people think of when they use the word "symbiosis."


What do you need to know to answer this question? animals, the remora and the shark, work together.

What does abiotic mean?


http://www.jjanthony.com/kudzu/ animals, the remora and the shark, work together.

Kudzu is native to Japan and China, however it grows well in the Southeastern United States. Kudzu is a vine that when left uncontrolled will eventually grow over almost any fixed object in its proximity including other vegetation. Kudzu, over a period of several years will kill trees by blocking the sunlight and for this and other reasons many would like to find ways to get rid of it.


Sunlight, animals, the remora and the shark, work together. an abiotic component in the environment, provides photosynthetic plants, which are biotic components, with energy for them to grow and pass on the energy to other members of the ecosystem.

The Physical and Chemical components of an ecosystem are called the “abiotic factors” and include:

  • The atmosphere

  • Climate and water

  • Soil structure and chemistry

  • Water chemistry

  • Seasonality

Follow the arrows. There is a difference between animals, the remora and the shark, work together. providing energy and receiving energy.

What do you need to know in order to answer this question?


Food Web animals, the remora and the shark, work together.


Mutualism: animals, the remora and the shark, work together.

  • A mutualistic relationship requires a positive interaction between both species of the pair.

  • If the food reward is large enough, the pollinator is likely to go looking for flowers of the same plant species after it is done visiting the flowers of the first individual.

  • A flower gets its pollen passed from one individual to another. In turn the flower provides a food reward in the form of nectar (a sugar rich solution), or pollen as a solid food source.

What does commensalism mean? animals, the remora and the shark, work together.

  • Commensalism animals, the remora and the shark, work together. means literally 'at table together'.

  • This is a symbiotic relationship between two species in which one species benefits and the other neither benefits or harms.

  • Often, the host species provides a home and/or transportation for the other species.

  • Commensalism: Barnacles on whales (barnacles benefit, whales are unaffected)

  • The flow of animals, the remora and the shark, work together. energy is transported through the animals by a system biologists call the food chain.

  • Krill are at the bottom of the food chain in Antarctica. If they die out everything else above them in the food chain will be adversely affected.Krill is a general term used to describe about 85 species of open-ocean crustaceans known as euphausiids. They are prey for myriads of surface feeding predators such as seabirds, squid, fish and whales.

If snakes are removed from the food web, then the only food source left for the hawk will be the rabbit .

Follow the arrows from the bottom up.

A food chain is the sequence of who eats whom in a biological community (an ecosystem) to obtain nutrition.
