Commensalism

The Caribbean Sea in located off the coast of North, Central, and South Americas. This sea spans about two million, seven hundred and fifty-three thousand square kilometers. There are also many islands found in the midst of the Caribbean Sea. While these islands are a great place for a vacation, the populations of people on the islands can affect life. Many different factors influence life in the Caribbean Sea. These factors are divided into two categories; abiotic factors and biotic factors. These

species have an interaction with another that is beneficial to the animal. There are different types of a symbiotic relationship, these include Parasitism, when one organism is benefited from a host animal who is harmed through the interaction, Commensalism, when one animal benefits and the other is not affected and stays neutral, and Mutualism, when both animals are benefited from interaction. Although there are three different types of relationships, some of them may occur in different places within

(periwinkle) - Austrolittorina cincta (sea snail) - Actinia tenebrosa (sea anemone) These organisms were all well adapted to the environment and tidal condition of the rocky shore. They show zonation and inter-relationships; competition, predation and commensalism. The main abiotic factor of the rocky shore was the movement of the tide creating aerial exposure. Zonation at the rocky shore was distributed in very distinct horizontal bands that formed visible zones on the intertidal rock zones. This is due

1. The heart symbol, the popular icon for the heart, can be traced to before the last Ice Age (PBS). A cultural hearth is a heartland, a foundation of a major culture. Cultural hearths are civilizations that have cultural influence around the world (Briney).  There are seven main culture hearths which includes Mesopotamia, the Nile Valley, Indus Valley, Ganges River Valley, Mesoamerica & S. America and Andean America (Briney). Many of the ideas and improvements that start up in these hearths spread

innovation will ever be able to make the length between different human net worth and statuses equal zero. While this is a valid argument, perhaps, the society as a whole should at least strive to reach commensalism, in which one benefits but the other is unharmed. Then, in order to surpass commensalism and enter mutualism, the individual people of society, rather than the society as a whole, need to make a change in their subliminal beliefs about the values of other human

BI 222 Discussion Leader’s Worksheet Your name: Emily Hansen Name of Taxon (clade): Chondrichthyes and Osteichthyes Description How do they… Obtain food They are predators; mostly carnivores that feed on fish, squid, molluscs, crustaceans and marine animals; some are herbivores that feed on plankton. They can also be filter-feeders or scavengers. They are heterotrophs and predators; they can be omnivores, herbivores, carnivores, or detritivores. Some species use suction feeding, in which they

of the tubeworm growing across the ribs was recorded. Most specimens of Cornulites appeared clustered along the commissure of the brachiopod, supporting the hypothesis that these organisms were filter feeders and the symbiotic relationship was commensalism. In contrast Spirorbis preferentially colonized shallow ribbed hosts or the lateral surfaces of angular ribs on brachiopods, with their settling patterns reflecting this difference. Unlike Cornulites, the Spirorbis larvae did not appear to settle

Life is defined by all the living creatures on earth. Biology is a broad topic of the study of life. Biology contains many different types of subjects within it that may be studied, like terrestrial or aquatic animals, or viruses and diseases. Here I will be talking about twelve of the millions of parts: Characteristics of life and kingdoms, biomolecules, nature and the importance of water, cells, energy and the carbon cycle, cell division through mitosis and meiosis, the central dogma through DNA/RNA

decomposers play? What organisms function as decomposers in most communities? 7. Can two species have the same niche in a community? Why or why not? 8. What is parasitism? What are some examples of parasitism? 9. What is the difference between commensalism and mutualism? 21.3 Energy Flow in Ecosystems 10. All organisms need energy in order to grow, reproduce, and perform the activities necessary for survival. Where does this energy come from ultimately? 11. How does sunlight energy enter the

Bryce Biology 2/24/16 Animal Paper The Badger The American badger is found in regions of North America from southern Canada and down through Mexico. They usually stick to open grassland ranges. Badgers Diet Badgers are carnivorous animals eating mostly pocket gophers, prairie dogs, ground squirrels, pika, woodrats and kangaroo rats. They usually do this by digging the prey out of the ground in their dens or chasing them down. Abiotic
