What is the difference between top-down and bottom-up control in an aquatic ecosystem? Give an example for a lake and an ocean.
Step by step
Solved in 2 steps
- A conceptual model representing the role, interaction, reaction, and density of essential ecosystem components is shown below. Examine the model and the relationships between the major players (i.e., predator, prey, producer). The structure's most important role is played by these major players. It's also worth noting that nutrition has been included in the model. This is the abiotic component that has a direct or indirect impact on the interaction. Question: Based on this scenario, what is the most significant role of sea otters in the marine community? Why it’s important?A conceptual model representing the role, interaction, reaction, and density of essential ecosystem components is shown below.

Question: Why does the organism’s interaction appear in an oscillating pattern? What does it suggest?http://www.fao.org/nr/water/aquastat/data/query/index.html?lang=en. Step 1. Choose five nations (including the United States) from the enormous database by clicking the corresponding boxes. For "select variables", choose these three: 1. Under "Water Resources" choose "Total Renewable Water Resources" and within that choose only "Total Renewable Water Resources per Capita. 2. Choose "Water Use" and then "Pressure on Water Resources" . Within that subset choose only"SDG 6.4.2 Water Stress". "SDG" means the Sustainable Development Goal. This value is the percentage of total available water that is used by a nation. 3. Under "Water Use" choose "Water Withdrawal by Sector", and within that choose only "Total Water Withdrawal per Capita". Nation Resources per Capita Withdrawal per Capita % Water Stress: withdrawal vs. resources) Step 2. Based…
- 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…What is a trophic cascade? How do you integrate the concept into ecosystem management programs and decision-making?What do you think are the multiple problems that aquatic environments are exposed to? What are the causes if these problems and where do they come from? List down at least three, which you think are major problems faced on aquatic environments. Explain briefly why you think these are major problems.
- The direction of the arrows in a trophic chain (as the one in the figure below) represents... A E O B) direction of movement of matter O Both B and C O A, B, and C O A) direction of consumption, from higher level consumer to lower level consumer O C) direction of movement of energy O Both A and CA given ecosystem has the following amounts of energy available at each trophic level: Primary producers: 4,000 gC/m2/day; Primary consumers: 480 gC/m2/day; Secondary consumers: 72 gC/m2/day; Tertiary consumers: 24 gC/m2/day. Does this ecosystem follow Lindeman's Law for ecological efficiency? No, the average efficiency is 20% O Yes, the average efficiency is 10% O No, the average efficiency is 10% O Yes, the average efficiency is 20%An ecologist studying the availability of nutrients and the distribution of the plants that live in this habitat is working at this level.
