An example of a biotic component of an ecosystem。
What is something living? Ex. Fungi, plants, animals.
Two fish species in a single lake evolve from a single ancestor that once lived in the lake. This is a description of a(n)
what is sympiatric speciaciton?
This will lead to an increase in the carrying capacity of the global human population.
What is increased technology, eating more low tropic level meals?
The GPP of an ecosystem is 3.6 kg C/m2/year, and the energy used by the producers for respiration is 1.2 kg C/ m2/year. Calculate the NPP of such an ecosystem
What is 2.4 kg C* /m2*year ?
beijing's biome
what is temperate grassland？
The trophic level of eagles that consume fish that consume zooplankton that eat algae.
What is tertiary?
The range of abiotic and biotic conditions under which a species actually lives is the definition of a(n)
What is fundamental niche?
As a country moves into stage 2 of the demographic transition, you would expect replacement level fertility to and crude death rate to do this.
Using your knowledge of your local area, predict how anthropogenic activity could affect, or has already affected, the biodiversity of local ecosystems.
What is the local area has become more developed (more businesses, homes, schools, new roads). This has resulted in habitat destruction and fragmentation. Also, we have invasive species and very few native species?
The TFR (total fertility rate) of a country with a one Child policy that everyone follows
What is 1?
Small inputs of this substance, commonly a limiting factor in aquatic ecosystems, can result in algal blooms and dead zones.
What is phosporus?
A stream divides a single turtle population into two isolated populations that evolve into two species. This describes a(n)
What is allopatric speciation?
Vietnam, there were 16 births and 6 deaths out of every 100 people in the year 2011. Using the rule of 70, estimate the doubling time for Vietnam’s population.
What is 7 years?
The initial dissolved oxygen reading was 6.3 mgO2/L. After 3 days, the bottle exposed to light had a DO reading of 8.7 mgO2/L, and the dark bottle had a reading of 3.2 mgO2/L. Calculate the NPP in mgC/L/day
What is 0.3 mg C/ L* day ?
The replacement level fertility in developed countries
What is 2.1?
A particular plot of land can produce 700 kg of beef per hectare. Beef sells for $4/kg. If that land is converted to producing corn, which sells for $0.15/kg, approximately this much money the farmer will make selling corn. Assume 10 percent ecological efficiency.
What is $1000?
Which sequence of secondary succession would be likely to occur after a fire in a forest?
What is bare soil, grasses and wildflowers, shrubs, sunlight-tolerant trees, shade-tolerant trees?
A city has a CBR of 17 and a CDR of 15. Ignoring immigration and emigration, this is when the population of this city will double
what is 350 years?
The study of islands is relevant beyond actual islands in our world’s contemporary landscape because of this reason.
what is the contemporary world can be viewed as a series of islands fragmented by human beings (using roads, and other manmade structures that break natural habitat into smaller pieces)?
my favorite new pet, the rat is this type of selected species.
what is r selected species?
The net primary productivity of an ecosystem is 1kgC/m2/year, and the energy needed by the producers for their own respiration is 1.5kgC/m2/year. The gross primary productivity of such an ecosystem would be this value.
What is 2.5kgC/m2/year?
The theory of island biogeography suggests that species richness is increased by these factors.
What is larger islands contain more niches?
If a population of 3.5 million people has a growth rate of 2.7 percent per year in 2010, this is the year the population would reach 14 million people.
what is 2062?
After Lab 5 about mortality rates: What are some things that you still do not know at the end of this lab? In other words, what are some new questions that have been generated by the study? How would you go about finding out the answers?
Was everyone in the area buried in this cemetery? I wonder about the cause of death for the people. Was there an epidemic in the area? Etc...
The author mentions that 1 kg of soybeans contains about 2.5 times as many calories as 1 kg of beef. Therefore, 1 ha of land would produce 25 times more calories when used for soybeans than when used for beef. What other questions would we need to ask to get the full picture?
how do grams of protien compare between beef and soybeans?
3.5 of 100g=soybean vs 20 g per 100 grams beef
