Question

population growth patterns
j - curve (exponential growth)

• population grows
• eventually hits factors
• can lead to population

carrying capacity

• the population size an ecosystem can support
• populations that overshoot may experience

reproductive strategies
r - selected species

• have offspring
• reproduce
• usually species
• can bounce back from population crashes

k - selected species

• have offspring
• reproduce in life
• live for a time
• usually species (like mammals)
• take longer to from population losses

human impact example: deer population

• humans removed like wolves and coyotes
• deer populations without natural predators
• deer cause damage to:
• life
• crops
• spread disease
• cause accidents
• we were worried about predators attacking our
• we keep bringing the of woods closer as we develop more land

population sampling methods
scientists use different techniques to count populations:

1. quadrat sampling - using areas to count species

Explanation:

This is about ecological concepts. In exponential (J - Curve) growth, population grows rapidly and continuously until it hits limiting factors which can cause population crashes. Carrying capacity is the maximum population size an ecosystem can support, and over - shooting can lead to die - offs. r - Selected species have many offspring, reproduce quickly, are usually small species and can recover fast from crashes. K - Selected species have few offspring, reproduce rarely in life, live long, are usually large species and take long to recover from losses. In the deer example, humans removed predators, deer populations increased, causing damage to wildlife, crops, spreading disease, causing car accidents, we were worried about predators attacking livestock, and land development reduces forested areas. Quadrat sampling uses defined areas to count species.

Answer:

• Population Growth Patterns (J - Curve): rapidly, continuously, limiting, crashes
• Carrying Capacity: maximum, die - offs
• Reproductive Strategies (r - Selected Species): many, quickly, small, quickly
• Reproductive Strategies (K - Selected Species): few, rarely, long, large, recover
• Human Impact Example (Deer Population): predators, increased, wildlife, agricultural, tick - borne, car, livestock, edge
• Population Sampling Methods (Quadrat Sampling): defined
