- Discuss the relationships among populations, communities, and ecosystems.arrow_forwardWhat ecological approach is used in identifying a pattern of change in a community or environment?arrow_forwardINTRODUCTION: The environment may be changed by the things within the biotic community, as well as relationship between organisms and the nonliving environment. The carrying capacity of an ecosystem is the maximum number of organisms that an area can support over time. The density of a population may cause huge changes in the environment so that the environment becomes unstable for the survival of that species. Humans can mess up natural selection and have either a positive or negative effect. OBJECTIVES Graph data on the Kaibab deer population of Arizona from 1905-1939. Analyze the factors that caused the changes in the deer population. PROCEDURE: Before 1905, there was an estimated 4000 deer on almost 30,000 hectacres of land on the Kaibab Plateau in Arizona. The average carrying capacity of the land at that time was estimated to be about 30,000 deer. Being concerned about the low number of deer, President Theodore Roosevelt created the Grand Canyon National Game Preserve to…arrow_forward

"I started to put on weight by the time I was seven. There was no obesity in the family and I played out of doors getting plenty of exercise. I was encouraged not to overeat, though surrounded by energetic brothers I liked to compete with them in everything, including meal sizes. I weighed nine stone [126 pounds] when I was nine and was quite proud to be the heaviest girl in the class, but ashamed when I was 13 stone [182 pounds] at 13. I've had weight/eating problems ever since. " (https://www.bbc.com/news/magazine-19743173) Community Interpersonal Intrapersonal Institutionalarrow_forward
- Communities are often described by the major predator relationships present. the trophic levels represented by the most species. the abiotic factors that result in the dominant vegetative type. the dominant species that live within the community.arrow_forwardThe four key attributes of community structure are total number of species top-down and bottom-up effects trophic cascades the sum of interactions among all species physical attributes of a community, including biotic and abiotic factors primary producers species relative abundancearrow_forwardA conceptual model representing the role, interaction, reaction, and density of essential ecosystem components is shown below. Examine the model and the relationships between the major players (i.e., predator, prey, producer). The structure's most important role is played by these major players. It's also worth noting that nutrition has been included in the model. This is the abiotic component that has a direct or indirect impact on the interaction. Question: Based on this scenario, what is the most significant role of sea otters in the marine community? Why it’s important?arrow_forward
