(EC) (8) effect on species; extinction of species that are unable to adapt, especially ones with specialised requirements; limited opportunity for plants and some animals to spread to more suitable conditions as climate changes. (S) (9) effect on agriculture; increased growth of some crops and loss of others, and effect on productivity; possible redistribution to different parts of the world, and overall loss of agricultural land.
The global pressure of the human population is significantly altering the natural course of many of the earth’s systems. In Madagascar there are forests for cash crops, cotton, coffee, and tobacco has been so rapid that areas devoid of
Why are ecological pyramids shaped as pyramids? (1 point) A. because there is a large decrease in the amount of energy or biomass as you move from one trophic level up to the next B. because the movement of energy through the biosphere follows a path similar in shape to a pyramid C. because decomposers form a wide base of support at the bottom of a food web similar to the base of a
c) What are two foods you can combine to get this complete protein via mutual supplementation? 14. Describe each of the protein energy malnutrition states: kwashiorkor
a) Biotic describes a living component of a community; for example organisms, such as plants and animals. b) abiotic components (also known as abiotic factors) are non-living chemical and physical factors in the environment which affect ecosystems. c) Herbivores are organisms that are anatomically and physiologically adapted to eat plant-based foods. Herbivory is a form of consumption in which an organism principally eats autotrophs such as plants, algae and photosynthesizing bacteria. More generally, organisms that feed on autotrophs in general are known as primary consumers.
The middle value of the sucrose solution being .6M of sucrose had a decrease of 23.38%, if you just look at those three percentages on a graph it would reveal that it has a decreasing slope, therefore backup my claim that as you increase the Molarity of the sucrose the mass of the potato decreases. Also on the graph of the percent changes of the mass of the potato it looks like exponential decay as you increase the solution the decrease in mass is peaking, where the percent difference between .8M of sucrose solution and 1M of sucrose solution is very small compared to the rest of the percent changes. The errors bars on the percent changes of the potato are HUGE, meaning this lab has a lot of inconsistent data that this lab is not reliable. Where the mass of the potato were varied from the high and the low the same applies to the final mass as well. There was no consistency in how many grams the potato weighed for each sucrose solution.
1. Explain how the ecosystem was affected by the missing species for each round of the demonstration. a. Round 1 = Removing the trees from the ecosystem then flowers and plants wouldn’t get shade and wind protection. b.
___T____ Enzyme reactions can be slowed or halted using inhibitors. 3. Circle the correct effect. Raising the temperature slightly will [ increase | decrease | not change ] the rate of reaction Boiling temperature will [ increase | decrease | not change ] the rate of reaction. Changing the pH toward the optimal pH will [ increase | decrease | not change ] the rate of reaction.
Halweil points out that though the use of industrial fertilizers are producing bigger plants with more yield faster, when one depletes the soil of its numerous necessary nutrients down to a basic three, those grown with the use of the fertilizers will always lose to those developed in organic soils, when comparing nutritional values and benefits. As a result, those who are on the Western diet are overweight, overfed, and malnourished—which is responsible for various chronic diseases according to Bruce Ames, a Berkley biochemist. Ames’ research found that human cells take on cancerous mutations when they are deprived of certain vitamins and nutrients. He adds that consuming the necessary amounts of fruits and vegetables daily can avert this, but the odds of prevention seem bleak since approximately a fifth of American children and a third of adults actually consume the needed amount. Pollan concludes by suggesting that the food system is a vicious circle—being that those who eat nutritionally drained foods, will eat more of it, in hopes of reaching the point of being nutritionally satisfied, though they never will
What changes happening in Madagascar are posing challenges for lemurs? Give details about the sources, time scale, and types of change. From what I understand, destruction of the habitat is taking place as it normally does, much faster than the evolutionary process will ever be able to adapt to the new habitat. The evolution process for the adaptation of the primates, including the lemurs, in Madagascar took 60 million years. The lemurs are challenged by logging, and other lemurs as there are over thirty species.
