- A series of organisms listed in a way that shows which is a food source for another is called ______while ______is made up of multiple connected energy paths in an EcosystemThe type of growth that occurs in a population that grows by a constant percentage per year is________ . Does this form of growth add the same number of individuals each year?_______ What shape of curve is generated if this type of growth is graphed?______ Can this type of growth be sustained indefinitely?______In which one of the following species is temporary exponential growth seen the most? invasive fish insects trees
- The type of place where a species typically lives is called its _______. a. niche c. community b. habitat d. populationFor each organism, create a survivorship curve by plotting the given information in a line graph. Title each graph "Survivorship Curve for [name of organism]." The y-axis should be labeled "Survivorship" and contain low, medium, and high indicators. The x-axis should be labeled "Life Span" and contain young, middle-aged, and old indicators. American toads practice explosive reproduction. During the first warm days in spring, both males and females migrate from forests and converge on ponds. Reproduction is quick, taking only a few days. Females lay hundreds of eggs in jelly-filled sacks along the sides of the pond or stream. As soon as the eggs are laid, males and females abruptly leave the pond. Even before they hatch, the offspring are prone to high rates of predation. Many offspring die before they reach adulthood. Of the offspring that do survive, some will die in adulthood, and some will live their entire natural life span.A population of 300 fairy wrens colonizes a cloud forest without any other wrens in it. The cloud forest has a carrying capacity of 500 wrens. Fairy wrens have a maximum potential growth rate of 80%. How large will the fairy wren population be in two years (rounded to the nearest whole wren)? ***note that the current time frame is year 0. You will have to calculate years 1, and 2. 462 429 405 492
- Chestnut blight is a type of fungus that affects the American chestnut tree. The fungus wiped out a large portion of the trees. What type of density-dependent factor would the fungus be considered? diseases and parasites physiological change predation competitionThe goldenrod gall fly lays its eggs on the goldenrod plant. The larval fly causes the plant to form a structure called a gall in which the larva lives until it becomes an adult fly. The flies cannot reproduce without goldenrod. The distribution of the goldenrod gall fly is primarily determined by Group of answer choices -random chance -biotic factors -abiotic factorsA farmer uses a new pesticide. He applies the pesticide as directed by the manufacturer and loses at 15% of his crop to insects. A farmer in the next state learns of these results and uses three times as much pesticide and uses only 3% of her crop to insects. Each farmer follows this pattern for 5 years. At the end of 5 years, the first farmers is still losing about 15% of his crop to insects, but the second farmer is losing 40% of her crop to insects. How can these observations be interpreted on the basis of natural selection? please answer short
- A sudden natural catastrophe resulting in massive die-offs would be categorized as a density-________ limiting factor. Select one: Autonomous Reliant Dependent IndependentAs environmental conditions change, communities continue to go through succession toward a predictable climax community. True FalseThere 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 offspring
