WHAT IF? Suppose a developer proposes to clear-cuta forest that serves as a corridor between two parks. Tocompensate, the developer also proposes to add the samearea of forest to one of the parks. As a professional ecologist, how might you argue for retaining the corridor?
productivity in above-ground biomass increment is greater in the estuarine stand than the island
fringing stand
productivity in litterfall is greater in the estuarine stand than the island fringing stand
O productivity can be measured in part by measuring carbon in litterfall
O productivity can be measured in part by measuring carbon in above-ground biomass increment
subtracting above-ground biomass increment from litterfall provides the total productivity for a
mangrove stand

- A family travels from New York City to Costa Rica three times a year for a vacation. The family would like to purchase some forested land in the Catskills, keeping the trees intact as an offset to the carbon dioxide they produce travelling each year. How much forest must they purchase? Use the following assumptions to measure the carbon offset provided by this intact forest. • The biomass of the forest increases at an annual rate of 2.8 × 105 kg/ha. • The forest biomass is 45% carbon by mass. • There are four people in the family. • 0.2 kg of CO2 is produced each mile per person on the flight. • The round-trip distance is 4,500 miles. • There are 2.47 acres in one hectare. 1. Calculate the mass of carbon, in kilograms, that is accumulated and stored in 1.0 ha of this forest in one year. 2. Calculate the mass of carbon, in kilograms, that is emitted by the family as a result of their round-trip flights to Costa Rica each year. 3. Calculate the number of acres of forest that must be…arrow_forwardplease 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_forwardplease draw! make everything clear please!

You may add a diagram or illustration to support your answer. Planting mangroves is better than putting dolomite sand on the coast of the polluted Manila Bay.arrow_forwardUnit B - Rainforests are being clear-cut in order to make room for more profitable crops that can be used as biofuels. In Brazil, a monoculture consisting of fields of soya beans is being planted, replacing the native rainforest ecosystem that often consists of thousands of species. Unit B - Compare the previous rainforest ecosystem and the new monoculture ecosystem with respect to biodiversity and population size. Your response should include · an explanation of biotic limiting factors an explanation of abiotic limiting factors a discussion of the availability of habitats and nichesarrow_forward

What function/services of the ecosystem is highly depicted in this situation? Justify. For 3-5 sentences only* One of the wetland ecosystem which is subjected to this degradation and considered as heavy polluted lake in the Philippines Laguna de Bay (LDB) (Framework for Philippine Plant Conservation Strategy and Action Plan retrieved 2018). LDB is the largest lake in the country and amongst the largest in Southeast Asia. It is a significant natural resource, being the catchment of an expansive and environmentally important watershed (Israel 2007). The shorelines of LDB serve as important locations for industrial, commercial and tourism activities in the country. It plays an ecological importance because it serves as spawning areas for fish and a natural protection from floodsarrow_forward
