Concept explainers
To explain:
The definition of ecology, population and ecosystem.
Introduction:
The ecosystem consists of interaction between species and abiotic factors. The environment is made of two types of factors: biotic factors which include living organism and an abiotic factor which includes nonliving things.
To explain:
The ways in which gopher and mole compete for food.
Introduction:
The place where species can get food and fulfill their needs is called habitat. According to competitive exclusion principle, two species cannon coexist in the same habitat. In this case, species need to compete with other for food.
To explain:
The ways in which monkeys are able establish dominance in a group.
Introduction: The organism in species having better availability of the
To explain:
The way in which pollution harms crop plants.
Introduction: The pollution is increases in unwanted and harmful substances in the environment which leads to destruction of biodiversity and other resources. Crops are generally affected by pollution caused by synthetic pesticides and fertilizers.

- Why are studies of ecosystems more inclusive than studies of populations?arrow_forwardGive typing answer with explanation and conclusion define/explain the significance of ANY TWO of the following terms as they apply to conservation biology. use examples to illustrate your understanding of the term. 1) global living planet index 2) Pauly's shifting baselines concept 3) beta diversity 4) insurance hypothesisarrow_forwardGive organisms of any ecological relationship that show competition and survival in the environment. After, explain how it is related to the statement "Survival of the fittest" of Charles Darwin.arrow_forward
- An insecticide is sprayed that kills the grass blackberry bushes.explain how each of the other populations of organisms will be affected If all the trees in the area were cut down,the energy supply of which population would be most directly affected?How would an increase in the oriole population affect the ecosystem? How would an increase in grasshoppers affect the rabbit population? Using evidence from the food web,explain why it is called a food"web"arrow_forwardYou are studying two new species that have a mutualistic relationship. How would you determine if the mutualism is facultative or obligate? What types of observational data would you collect and what type of experiment would you conduct?arrow_forwardWhat is predator management? What is the linkage between the evolution of prey and predator species and how this relates to the regulation of population size? please answer botharrow_forward
- How does the study of population ecology help us understand why some populations grow, some remain stable, and others decline? a.) Why has human population growth, which increased exponentially for centuries, started to decline in the past few decades? b.) What is carrying capacity? Do you think carrying capacity applies to people as well as to other organisms? Why or why not?arrow_forwardBased on the images provided, the distribution of animals seen is dependent on which one of the following? Explain your choice. species population size community ecology spatial scale immigration and emigrationarrow_forwardWhich one of the following statements is FALSE? Beta diversity is low when two ecosystems share the similar species and respective abundance. An intelligent meander records date, time, location and a list of species. Beta diversity or differentiation diversity compares alpha diversity among several communities. Species richness is the total species abundance in an ecosystem. Inventory diversity can be defined by alpha diversity, which is the number of species in a local forest stand.arrow_forward
- How does the study of population ecology help us understand why some populations grow, some remain stable and others decline? The human population has grown as we have increased our global carrying capacity. In your opinion, can the global carrying capacity continue to increase/ Explain your answer? Why has human population growth, which increased exponentially for centuries, started to decline in the past few decades?arrow_forwardA niche is loosely defined as an organism's role in its environment, which can include factors like, feeding preference, nesting behaviors, mating behaviors, method of obtaining prey, and local habitats. Considering Gause's law, conduct research on the California Red Legged Frog and the Northern Pacific TreeFrog (use wiki or other google search). Create a chart that compares the two with regard to their niche or their lifestyle that may explain how these two native frogs have evolved to coexist in the same ecosystem. Northern Pacific TreeFrog California Red Legged Frogarrow_forwardSUBJECT : Biology - Ecology How would you describe the slope of a rank-abundance curve that vary with increasing species evenness?arrow_forward
