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

Please help me anwer this.

Find the flaws! Energy in a terrestrial ecosystem moves from the sun, to producer, to primary consumer, to secondary consumer, ending in a tertiary consumer. Producers are heterotrophs and consumers are autotrophs. Biomagnification in how the amount of toxin in an organism will increase as you move up a food chain. For example, a plant might only have a little toxin but an herbivore eats a lot of plants. So, now the herbivore has a medium amount of toxin. A carnivore eats a lot of herbivores and now the carnivore has a high amount of toxin and is sick. The water cycle has five important processes. Evaporation which is water turning into vapor. Condensation and precipitation refer to water vapor turning into liquid or solid water. Subsurface water flow feeds rivers and streams. Surface runoff is water from precipitation gathering in streams. Streamflow moves water from mountains to oceans. Carbon can cycle either quickly or slowly. “Fast” carbon cycling happens in biology.…

2 In a temperate grassland ecosystem, total primary production was 12,740 g/m/yr. Annual net secondary production by the herbivorous insect community was 320.5 g/m/yr. Total net tertiary production by spiders was 22.6 g/m/yr. Calculate the trophic efficiency from the first trophic level to the third trophic level.

Pls help ASAP.

Need help with questions 1 and 2 please: 1.) A population of beetles is introduced into an environment where conditions are ideal allowing the beet population to reach its biotic potential for many generations. This population of beetles shows A.) logistic growth B.) linear growth C.) per capita growth D.) exponential growth 2.) Biotic potential is the highest possible per capita growth rate for a population. Which of the following would limit the biotic potential of an organism ? A.) many offspring per reproductive cycle B.) many reproductive cycles in a life span C.) limited resources D.) a high percentage of offspring surviving long enough to reproduce

Q1) For primary producers such as plants, photosynthesis requires carbon dioxide (CO2), water (H2O), and sunlight. As a result of photosynthesis, plants produce glucose (C6H12O6) and oxygen (O2). The CO2 is used to make glucose. Energy from sunlight is used to power the reaction that creates the glucose molecules. The data set below is the results of a study that investigated how light intensity (distance from a light source; cm) affects photosynthesis (bubble production; #O2 bubbles) in Elodea (aquatic plant).   # of bubbles produced @ 5 cm # of bubbles produced @ 10 cm # of bubbles produced @ 20 cm # of bubbles produced @ 30 cm Group 1 0 9 7  0 Group 2 2  12 6  3 Group 3 2 9  9 2 Group 4 0  8 10 0 Group 5 1 10 7 5 Group 6 3  13 4 4 Group 7 3  10 8 4   Please identify the independent variable and the dependent variable in this study.
