Information about knowing where their predators would also be important as it would tell the plants that they need to execute a strong stimulus response that limits the potential danger. Thus heavy touches (heavy pressure) and other strong stimuli that indicate that predators are near would be reacted to by the plants. However‚ smaller constant stimuli‚ such as some mildly strong wind gusts and/or rain (depending

GLM results showed that the interaction of ‘time × different combinations of predators and aphids × ant’ (F = 0.211; df = 10‚ 317; P = 0.995)‚ ‘ant × time’ (F = 0.490; df = 2‚ 317; P = 0.613) and ‘different combinations of predators and aphids × time’ (F = 1.639; df = 10‚ 317; P = 0.095) on the survival rate were not significant. However‚ the interactions of different combinations of predators and aphids × ants

Evolution by Natural Selection *** Please review lesson 5.02 to help answer the questions Living things that are well adapted to their environment survive and reproduce. Those that are not well adapted don’t survive and reproduce. Any inherited trait that increases an organism’s ability to survive is called an adaptation. Remember that these adaptations are inherited traits; they are not changes that an individual chooses to make and that increases fitness‚ which is defined as the ability

It explains the selection on predators to become efficient and effective at detecting and capturing their prey. In an aquatic ecosystem‚ the sense of smell is important for many prey and predators. It explains how the nature and role of predator detect species‚ disturbance cues‚ and diet cues on their behavior. Predators that catches prey are unaware usually win and if prey with advanced
