Interdependent Relationships in Ecosystems: Environmental Impacts on OrganismsConstruct an argument that some animals form groups that help members survive. Analyze and interpret data from fossils to provide evidence of the organisms and the environments in which they lived long ago.
Examples: School of fish Herd Bird migrating together, finding food together Lions and wolves hunting in a pack Baboons defending other animals Algae feeding the planet Ocean Biology was covered in December: http://www.almadartebio.org/biology-page/week-of-1203-ocean-biology Construct an argument with evidence that in a particular habitat some organisms can survive well, some survive less well, and some cannot survive at all.
Water temperature affect the fish population People fishing affects the fish population Puffins need this species of fish to live Low fish population leads to puffin choosing not to lay an egg for the year Puffins move to another island People in Iceland are sad because they like to see puffins around Make a claim about the merit of a solution to a problem caused when the environment changes and the types of plants and animals that live there may change.
Tardigrade surviving dehydration Fairy shrimp in the desert Desert toads
Environmental change is a stressor Survival is natural Selection Things that can affect the ecosystem: Volcanic eruption Forest Fire Temperature Change Pesticides and herbicides Plague or infestation Nuclear bomb Examples: Pack social structure Lookouts Fish leaving the school of fish and making a new school of fish Evidence of Common Ancestry and Diversity
Examples: Genetic similarities between species Similar traits Protein in Birds' Eyes Helps Them 'See' Earth's Magnetic Field Called Cry4, the protein belongs to a group known to regulate circadian rhythms, or biological sleep cycles. Examples: Finch in Galapagos eating different foods Specialization bio-communities that we coveredSample questions for eocThe graph provided shows the population of an organism introduced to a new environment and how the population changed over sixty days  After the sharp rise, there was a leveling off of the population. What does this indicate? A. The life expectancy of the organisms in this population is about thirty days. B. This environment has only enough resources to support 250-300 individuals of this organism. C. This organism needs thirty days to reach maturity before it can reproduce. D. This species is unable to reproduce, in any habitat, beyond a population of around 300 individuals. It was originally estimated by scientists that the carrying capacity of humans on earth was approximately 1 billion people. The population of earth is now over 7 billion people. What is the best explanation for this? A. Humans have greatly exceeded their carrying capacity. B. Humans now consume less resources than they did previously. C. Humans have become more efficient in producing and replenishing food resources. D. The earth has continued to grow at the same rate as the human population has. An incomplete concept map of carrying capacity is provided.  Which of the following factors would most accurately be placed in the same side of the concept map as “Increase in population of competitors"? A. Increase in reproductive success B. Decrease in available living space C. Increase in availability of freshwater D. Decrease in population of predators It is possible that a particular species will exceed its carrying capacity in the short term. Which of the following will be the end result for the species? A. Population growth will continue to increase but at a lesser rate B. The population will level out and no longer grow. C. The population will crash and experience a sudden decrease or extinction D. Other species will increase as well in order to balance the ecosystem The populations of four species introduced into a new ecosystem are plotted, for the first one hundred days in the graph provided.  Which species was first to reach the carrying capacity of the ecosystem for that particular kind of organism? A. Species 1 B. Species 2 C. Species 3 D. Species 4 Animals engage in both individual and group behaviors. Which of the following is an example of an individual behavior? A. In a termite colony, different tasks are carried out by different types of termites. B. Monarch butterflies migrate long distances, traveling in groups of many millions. C. Juvenile chimpanzees model the actions of their parents and other adults. D. All members of an elephant herd will contribute to the care of any offspring. Most wolves hunt in packs while some individuals live and hunt alone. What data would be needed to support the claim that hunting as a group provides an advantage? A. The density of prey animals, measured in number of organisms per square kilometer, in the habitats of pack wolves and solitary wolves B. Hunting success, measured in kilograms of meat per individual per week, for wolves that hunt in packs and those that are solitary hunters C. The return on investment in hunting for the average wolf, measured in calories expended for hunting, divided by calories obtained in prey animals D. The number of different predator species in the habitat as compared to the number of different prey species Zebras live in large herds. When attacked by a predator, such as a lion, some individual zebras will engage in combat with the lion, rather than trying to escape. This behavior increases the risk of injury and death to the individual zebra. Why might this type of behavior evolve if it is so clearly a disadvantage to the individual? A. This behavior increases the survival advantage of other members of the herd and the species. B. This behavior ensures that only the strongest and most aggressive zebras pass on their genes. C. This behavior is an opportunity for zebras to prove themselves to potential mates. D. This behavior frightens predators in the area and makes future attacks less likely. Which of the following describes a survival advantage an individual organism derives from living in a large group with other individuals of the same species? A. They are less likely to contract a disease. B. They encounter reduced competition. C. They are less visible to predators. D. They can more easily find a mate. Which of the following animal behaviors could be disadvantageous to the individual organism, but increase the survival advantage of other members of its social group? A. Joeys stay within their mothers’ pouch for protection for several weeks. B. Newly hatched sea turtles will automatically begin moving toward the ocean. C. Squirrels vocalize loudly when they observe a predator in their habitat. D. Male peacocks compete for females with elaborate plumage and behaviors.
