What is often true of a population of organisms with a type Ill suvivorship curve?
they produce few offspirng and invest more energy in each offspring
they produce more offspring and invest little energy in each
they have low death rates during early life stages
they are equally likely to die at any age
When looking at fish populations the number of eggs produced at spawning is known as:
Group of answer choices

Carrying Capacity
For 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.

- Consider a trophiccascade with 4 levels: 1) predatory fish that consume planktivorous fish, 2) planktivorous fish that consume zooplankton,3) herbivorous zoplankton that consume phytoplankton, and 4) phytoplankton. True or False: A reduction in predatory fish will increase the level of phytoplankton. True Falsearrow_forwardFor 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. Andean condors reproduce slowly. Females lay one or two eggs every other year. The offspring that hatch are well-protected and cared for, and many reach sexual maturity at five to six years. Although their numbers are being threatened by human impacts, they are naturally long-lived, surviving for seventy to seventy-five years.arrow_forwardWould you classify these species as weak, moderate, or strong competitors?

- Please do these fast and please tell short answersarrow_forwardSince 1972, Dr. Jim Estes had been studying a food chain of kelp -> urchins -> sea otters, and then in the early 1990s orcas began eating the sea otters. The data collected by Dr. Estes are shown. Panel A shows sea otter abundance around four different islands from 1972 to 1997. Panel B shows the amount of sea urchins (sea urchin biomass) in 1987 and 1997. Panel C shows the amount of kelp that sea urchins ate over a 24- hour period (grazing intensity) in 1991 and 1997. Panel D shows the number of kelp plants within a specific area (density of kelp) in 1987 and 1997. The thickness of the arrows illustrates the strength of the effect one species has on the species below it in the food web. Sea otter abundance -Amchitka L N. Adak I. Kagalaska i. L Riskal.
