- Each of the following terms represents a type of economic value we place on the services we get from an ecosystem except one. Which one is NOT an economic value? O O 0 O Provisioning Indirect Bequest Existence DirectA keystone species is not necessarily abundant in a community but has a large impact on surrounding species and community structure. True O FalseThe four key attributes of community structure are total number of species top-down and bottom-up effects trophic cascades the sum of interactions among all species physical attributes of a community, including biotic and abiotic factors primary producers species relative abundance
- Communities are often described by the major predator relationships present. the trophic levels represented by the most species. the abiotic factors that result in the dominant vegetative type. the dominant species that live within the community.There are two types of life strategies used by organisms to survive in their environment. 1. K-selected strategy - growth rate is near the carrying capacity 2. r-selected strategy - growth rate is near biotic potential Match the characteristices below to the life strategy they represent J-cruve Logistic Growth Long life span Few offspringMatch the approach to protection with the example from the academic literature. Species approach Hotspot approach Ecosystem approach 1. Wolf reintroductions into the Yellowstone environment restored riparian species and increased biodiversity because wolves controlled the numbers of elk and coyotes which allowed plants, beaver, and foxes to rebound (Ripple and Beschta 2003). 2. The creation of a reserve protects the red-brown treecreeper (Climacteris picumnus). This approach looks to accommodate processes that threaten species viability, such as fragmentation and feral predators (Nicholson et al. 2013). 3. Species richness of tiger beetles, Cicindelidae, is positively correlated with bird and butterfly diversity across North America, Australia, and the Indian subcontinent (Reid, 1998).
- As related to ecosystem services which term is accurate match for direct service 1- the benefits humans receive from ecosystem processes 2- a product from the ecosystems biodiversity 3- the monetary value of a productA 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?Choose the Management Principle that best describes the picture provided. WORLD ANIMAL PROTECTION O environmentally Sustainable development O precautionary principle conservation of biodiversity O intergenerational equity
- Biotic factors are the living factors that affect living organisms, they include • Availability of food • Pathogens and parasites New predators Interspecific competition • Write a sentence for each of these factors explaining the consequences of them on living organisms chances of survivalDefine natural capital. Define natural resourcesand ecosystem services, and give two examples ofeach. Give three examples of how we are degradingnatural capital.
