To review:
The ecological trade-offs that occur in mussel farming and whether the addition of sea cucumbers should be considered an ecosystem service.
Given:
Mussel culture in a coastal farm is causing a critical pollution problem as the waste generated by the mussels is being released into the water and is resulting in hypoxia or low levels of oxygen.
Introduction:
Aquaculture such as mussel farming can cause a huge impact on the ecosystem as the waste generated by the mussels to get released into the water. This increases the organic content in the water and can lead to hypoxia or low levels of oxygen, which is detrimental to the other organisms living in the particular aquatic ecosystem. Thus, it causes a serious problem of pollution.

- With antibiotic resistance rising, researchers are looking for ways to reduce the use of antibiotics. Instead of antibiotic-laced food, some cattle now get probiotic feed with cultured bacteria that can establish or bolster populations of helpful bacteria in the animals gut. The idea is that if a large population of beneficial bacteria is in place, then harmful bacteria cannot become established or thrive. Explain the ecological principle that is guiding this practice.arrow_forwardLook at the pictures below. One picture showe a rainforost environment, and the other shows a dooort onvironment. Many rainforost plants have large, fat leaves. Many dosert plants have small neodio-iko loavos. What is the best reason for this difforence? (SC.SL.17.1) P O The plants are different ages. O The plants in the desert do not reproduce. O The plants are adapted to the conditions of their environment. O The plants carry out pholosynthesis in different waysarrow_forwardWhat will the loss of biodiversity cost us in the long run? Briefly explainone long term impact.arrow_forward
- Lets say we shift toward ocean mining and we disrupt deep ocean ecosystems, which are biodense, and have a lot of biodiversity. Do you think this information would prevent ocean mining? Why or why not?arrow_forwardA 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.

Why are desert ecosystems vulnerable to long-term damage? How dodesert plants and animals survive? Explain how thethree major types of grasslands differ in their climateand vegetation. What is a savanna? Explain howsavanna animals survive seasonal variations in rainfall (Core Case Study). Why is the elephant an important component of the African savanna?

- Stream orders 1 and 2 are generally shaded by tree canopy overhanging the streams. If you cleared the trees light will reach the stream. Why don't we see phytoplankton colonizing this site?arrow_forwardWRITE ABOUT A THEME: Energy and MatterDecomposition typically occurs quickly in moist tropicalforests. However, waterlogging in the soil of some moisttropical forests results over time in a buildup of organicmatter called “peat.” In a short essay (100–150 words), discussthe relationship of net primary production, net ecosystemproduction, and decomposition for such an ecosystem. AreNPP and NEP likely to be positive? What do you think wouldhappen to NEP if a landowner drained the water from atropical peatland, exposing the organic matter to air?arrow_forwardThe figure above shows main abiotic and biotic factors influencing the physiology and behavior of fish larvae in estuaries. The more important the factors are for the larvae, the thicker the lines. Suppose changes from question 1 take place. Draw a new figure and redefine the thickness of the lines and new factor interactions. This is from question 1 : A proposal is made to deepen the entrance and main channel of an estuary. What do you suppose will happen to the salt marshes that surround the channel? What do you predict will happen to the productivity of the estuary? Deeper channels would probably change the mixing of the fresh and saltwater and lead to increased salinity and changes in the salt wedges in the channel. This would probably negatively impact the plants on the edges of the channel, as they would have to deal with higher salt levels than they are adapted to. The strain that would be put on the plants (like cordgrasses) in the marshes, would most likely lead to a…arrow_forward
- You will be examining the relationship among organisms inhabiting a small lake. Examine the “Lake Inhabitants” sheet for information about the organisms found in the lake. What biotic and abiotic factors will affect the aquatic plants in the lake? What biotic and abiotic factors will affect the bluegill in the lake? Looking at the organisms associated with the lake, organize them into three trophic groups: producers, consumers, and decomposers. Separate the consumers into three subcategories: herbivores, carnivores, and omnivores. Create 3 different food chains found within the lake. Food chain #1 should contain 3 organisms, food chain #2 should contain 4 organisms, and food chain # 3 should contain 5 organisms. The arrows should point in the direction the energy is flowing through the food chain. You can either use the “>” as your arrow or the Insert Symbol function to insert an arrow into your food chains. As the energy flows through each trophic…arrow_forwardHow would you our reconcile the emerging needs of human beings regarding their health and the need to protect the growth of biodiversity? Do you think that earth can exist without human beings taking care of it? Or biodivesity also needs human beings for it to be in continous growing process? What are small ways that you think would promote safekeeping our biodiversity? What do you think are the common human activities that can harm biodiversity? What would be the consequences if these human activities might be stopped and prohibited?arrow_forwardHow has the invasion of zebra mussels in the Hudson River affected 1 biotic or abiotic factor in the river ecosystem?arrow_forward
