- Why are food chains relatively short? O Not enough energy is transferred from one trophic level to the next to support a longer chain. O There are not enough species of carnivores to make the food chain longer. O Longer food chains require more land that is found in today's fragmented habitats. There aren't enough different plant species to support enough herbivore species to support the number of carnivore species needed for longer food chains.Can somone help me to answer 2 question after watching a video, Thank you https://www.youtube.com/watch?v=M18HxXve3CM 1)What is one interesting or surprising thing you learned from the video you watched? 2)It’s unlikely that you personally hunt wolves or whales, and equally unlikely that you are responsible for importing rabbits and foxes to Australia as shown in these videos. But your actions do affect ecosystems. What is one thing you can start doing or stop doing right away to help protect the earth’s ecosystems? Explain how the thing you chose helps to protect ecosystems.aungn opy and complete the following table to classify each animal in its rrect feeding group. Herbivore Predator Scaveng Example Give an example of each of the following fom the school grounds a producer, a predator and a camivon Look at the pictures of carmivores and herbivores on pages 23 and 24 )What do carnivores eat? ) What do herbivores eat? )Suggest how carnivores and herbivores are suited to getting and eating their food.
- In terms of trophic levels and energy, why do you suppose that there are not many top predators around?In any scientific paper, the Discussion is often the most hard-hitting, and where researchers elaborate and explain their results in the context of their experiment and the real world. Explain why when researchers tried culling some of the elk herd it did not have trophic effects, while reintroducing wolves did have trophic effects.Indentify the correct food web for each question. Which type of food web cycles materials and moves energy into and out of the community? Grazing Which type of food web is dominant in Central Park's forests and pond? Detrital Which food web includes humans? Grazing
- What forces would be working against an equitable distribution of our resources?A Food Web om Eage Pythan Wolf Rat Dragonfly Thrush Frog Butterfly Fruit Fly Grasshopper Mangoes Corn A Flowering Plant Lavenders Look at the food web above to answer the following questions. 1. Which organisms are the producers in this food web? 2. Which organism is an example of a primary consumer? 3. Which organism is an example of a tertiary consumer?Explain the effects on the ecosystem if Wood rat were removed. Provide both positive (if any) and negative impacts on the ecosystem. Be sure and include as many of the following terms in your writing as possible: autotroph, heterotroph, producer, primary consumer, secondary consumer, tertiary consumer, carnivore, omnivore, herbivore, energy, population, increase, and decrease.
- Part B-Interactions in the ecosystems Throughout this unit we have been examining how an organism Interacts with the living and non-living elements in an ecosystem. We Fve discussed and investigated predator/prey relationships as well as Tood chains and webs, Now it is time to put that knowledge into practice and explore some of the interactions between different components in your ecosystem apply it. Your Goal: Using the model ecosystem you have just created, you will generate one food chain/web. Method 1. Using your model, show 1 food web that contains at least 8 elements. You must include a producer, consumer and a secondary consumer. They must be realistic feeding relationships! (You may need to add an element to your ecosystem model). Remember, a food web contains many food chains; make sure your consumers have a variety of food to eat. a primary Önly for the elements in your food web - add to their labels whether it is a producer or consumer. Each consumer must be labelled as a…The trophic pyramid has very few large predators at the top and increasing numbers of creatures as you go to lower levels of the food chain. Why is that? If there are lots of prey animals in a system why aren’t there just as many predators?The Atlantic cod population is of primary economic importance to fishingcommunities throughout the maritime provinces in Canada. Unfortunately, thispopulation has underwent an extreme collapse in recent years due to overfishing.Some argue, however, that the collapse of the cod population may actually beattributed to an increase in the population of harp seals, a known predator ofcod. One suggestion to help cod stocks recover is therefore to permit the huntingof harp seals on a large scale. Suggest and explain one potentially negativeconsequence of limiting the harp seal population.
