Question
Chapter 31.4, Problem 3CC
Summary Introduction
To propose:
A hypothesis explaining why a population of plants growing in a breezy location is more prone to herbivory by insects than the population of same species of plants growing in shelter.
Concept introduction:
Over the course of evolution, plants have developed elaborate mechanisms to protect themselves from herbivory. This includes chemical defense (release of toxiccompounds like lignins, cannabinoids and more), mechanical defense (thorns, resins and so on), indirect defense (attracting the enemies of the herbivores), camouflaging, mimicry and leaf shedding and colour.

Scenario 4: On your frequent trips to Costa Rica you have seen that there are certain trees that have
ants that live on them and the same species of trees without ants. Trees that have ants living on them
show little sign of being eaten by herbivores (deer, cows, etc.), but trees without ants are severely injured
by herbivores. You think that ants may protect these trees somehow from herbivores.

- Ragwort is a noxious weed. It is a major problem in Victoria’s Strzelecki, Otway and Dandenong ranges. More than 1000 dairy farms are affected by the weed. Biological control involves introducing a living predator (plant or animal) to control the species rather than using a chemical pesticide. Researchers are examining the use of beetles and moths as a biological control for ragwort. The beetles and moths will feed on the weed. This is an alternative to using chemical pesticides to kill the ragwort. For biological control to contribute to ecologically sustainable development, it is essential that. pesticide companies maintain profits. food production is high in all regions. there is community support for biological control. biological control does not degrade the environment for future generations.arrow_forwardCONTEXT The earth is comprised of many different life forms, including plants, animals, humans, and other organisms. These various life forms are highly interdependent and have formed important systems that continually reshape the planet's landscapes, oceans, and atmospheres. Booming human population growth over the last two centuries has put, and continues to put, many of these life-sustaining systems out of balance and in serious jeopardy, endangering many of the plant and animal species that human beings directly and indirectly depend upon for long-term survival. Bigger human populations naturally mean increases in human activities worldwide, leading to changes in landscapes, oceans, atmospheres, and the path of human history. For example, as noted in the benchmark of this lesson, human activities like reducing the amount of forest cover, increasing the amount and variety of chemicals released into the atmosphere, and intensive farming, have changed the earth's land, oceans, and…arrow_forwardExplain in short plz. Asap. Thanks Imagine a population of cacti living on an imaginary island called Plantopia. These cacti evolved to stop producing spines because there are no herbivores on Plantopia. Every year, a few cactus seeds are washed onto the shores of Plantopia from the mainland. There are many large herbivores on the mainland. (Tip: Try drawing the scenario to help you visualize it.) Name three mechanisms of evolutionary change ( 3 of mutation, natural selection, genetic drift, andgene flow.) that may be acting on alleles for spine production on Plantopia. For each mechanism, explain what effect it may have on spine production, and whether this change is adaptive or non-adaptive.arrow_forward

If the palm populations can be harvested in a sustainable manner at the same rate at which they can potentially grow, then what was the estimated maximum sustainable annual harvest rate for the palms? What was it for the parrots? Based on data originally given in the scenario, recall that the area is 10,000 km2, that 10 km2 hosts 1 parrot (of any age) and 1,000 palms, that felling every thousandth palm kills a nesting pair of parrots, and that carrying capacities for each species are twice their current densities. You now have all the information you need to address the question at hand: 12. If the palm population is harvested at its maximum sustainable limit, will the parrot population be at risk?

Sun and Earth supply 6 units of energy to each plant. For higher tropic levels, individuals consume 2 units of energy each before passing the remainder to the next trophic level. The number of individuals in each trophic level is given below. Complete the table below by computing for the number of energy units in each column. Answer the following questions: Discuss how the food chain works. Where does each trophic component or level get its energy (food) from? What is the ultimate source of energy for all components of the food chain? Which component got the highest amount of available energy/individual? Why do members of this component need the most energy?arrow_forward
- please draw! Create a model which accurately, in detail, depicts the potential pathways of carbon (biomass) and energy in an ecosystem with at least five trophic levels (don’t forget your decomposers, they can count as one trophic level). Make sure to incorporate the multiple pathways that biomass and energy could take at each trophic level. Lastly, clearly illustrate how carbon and energy flow in this ecosystem. Be sure to include adequate levels of detail for all pathways and differentiate the flow of carbon and energy in your model.arrow_forwardDescribe why biodiversity is important to ecosystem health, even in an agricultural setting where mo… Show more Describe why biodiversity is important to ecosystem health, even in an agricultural setting where most often farmers are paid for a single, pure product like wheat or corn.
