What is the relationship between zebra mussels and native fish?
Zebra mussels are not native North America; they were brought here by ships travelling from Europe. They reproduce quickly and filter out plankton from the water reducing food for native fish.
Which relationship is shown in the graph competitive exclusion relationship?
The answer would be the last one: predator-prey relationship.
Why are zebra mussels a problem in the Great Lakes quizlet?
How have bodies of water not connected to the Great Lakes become infested? When zebra mussels attach themselves to the openings of native mussels while the native mussels are closed, the native mussels are unable to open and close their valves, so they are unable to get food and water and they die.
Why is Shell considered biotic?
In biology, a shell is defined as a protective structure of mollusks and crustaceans. A shell is considered to be biotic because it came from something living. Shells are not in fact alive as they are made of calcium carbonate and in some cases α-chitin, two non living materials.
Why Zebra mussels are bad?
In spite of their small size (often no bigger than a penny) zebra mussels cause far-reaching damage to water structures and native ecosystems. They also negatively impact aquatic ecosystems by harming native organisms. In huge numbers, they out-compete other filter feeders, starving them.
Can you eat zebra mussels?
Are Zebra Mussels edible? Most clams and mussels are edible, but that does not mean they taste good! Many species of fish and ducks eat Zebra Mussels, so they are not harmful in that sense. To be safe, it is not recommended to eat Zebra Mussels.
Why is P Aurelia outcompete P Caudatum?
The competitive exclusion principle states that two species cannot occupy the same niche in a habitat. But when they are placed together in the same test tube (habitat), P. aurelia outcompetes P. caudatum for food, leading to the latter’s eventual extinction.
What is an example of competitive exclusion?
The principle of competitive exclusion was proposed by G.F. Gause which states that two species competing for the same resources cannot coexist. Another example of competitive exclusion is, the red squirrels replacing the grey squirrels in Britain.
What are the three possible outcomes of competitive exclusion?
Instead, three potential outcomes can result from strong interspecific competition: competitive exclusion, local extinction and niche differentiation. Competitive exclusion occurs when one species outcompetes another in a part of its habitat so well that the second species is excluded from that part.
How do zebra mussels make it to the United States quizlet?
Zebra mussels first entered North America in about 1986, when foreign ships apparently dumped the larvae with ballast water into Lake St. Clair; Within six years, zebra mussels had spread to all the Great Lakes and had entered eight large river systems. As a result, zebra mussels have spread beyond the Great Lakes.
How are humans trying to control zebra mussels?
What you can do to stop the spread of the invasive zebra mussel: Inspect boat, trailer, and other recreational equipment that have been in contact with water. Remove all mud, plants, or animals. Drain all bilge water, live wells, bait buckets, and all other water from your boat, engine and equipment.
How were zebra mussels introduced in the United States?
The zebra mussel is native to Eastern Europe and Western Russia. The species was unintentionally introduced into the United States ‘ Great Lakes through the discharge of contaminated cargo ship ballast water.
Is rotting carcass a biotic factor?
The biotic factors are those that are living components that affect the population of the other organisms. From the given choices, the answer would be “A. rotting carcass “. Although it is already dead, the fact that it is from a living organism makes it a biotic factor.
Why is a shell considered a biotic quizlet?
It is non living and abiotic. Why is a shell considered to be biotic? It comes from something living.
Is soil biotic or abiotic?
Soil is composed of both biotic —living and once-living things, like plants and insects—and abiotic materials—nonliving factors, like minerals, water, and air. Soil contains air, water, and minerals as well as plant and animal matter, both living and dead.
