Blank-- is an interaction in population ecology, whereby members of the same species compete for limited resources.

Intraspecific competition

Sundews (Drosera spp.) are carnivorous plants that secrete a cocktail of BLANK from their tentacle glands to digest insect prey, enabling nutrient absorption (especially nitrogen and phosphorus) in nutrient-poor habitats. These enzymes operate in an acidic environment, typically provided by the mucilage secreted upon prey capture.

hydrolytic enzymes

Blank-occurs when members of different species compete for a shared resource

Interspecific competition

Blank and blank capture and feed on insects- each reducing the amount of food for each other

Wolf spiders and sundews (carnivorous plants)

THIS IS? “Whenever 2 species require the same limited resource to survive or reproduce, the better competitor will drive the less competitive species to extinction in that habitat”

Competitive Exclusion Principle

“Whenever 2 species require the same limited resource to survive or reproduce, the better competitor will drive the less competitive species to extinction in that habitat” THIS PRINCIPLE WAS SAID BY?

BLANK – BLANK – captures, kills and eat another organism- the BLANK

Predation

Predator

prey

An interaction where one organism kills another for food

Viceroy butterfly

Blank-one species resembles another organism

Mimicry-Mimic

Blank-blending with the environment to escape predators

Camouflage

Blank-– Parasite - withdraw nutrients from another organism ( host )

Blank-is a type of symbiotic relationship between two organisms in which one benefits without affecting the other one in ANY WAY.

Commensalism

Blank-is a type of symbiotic relationship between two organisms in which one benefits without affecting the other one in ANY WAY.

Commensalism

a hard, keratinous plate or scale that covers the bony shell of a turtle or tortoise.

Scute

Blank-both organisms benefits from the interaction

Blank-is a biological interaction between two species wherein both the species benefit from each other

Mutualism

A unique relationship

Blank-steal parental care

Blank and blank-Play eggs on nest of other birds

Brood Parasites

Cuckoos and cowbirds

Blank-insects that lay their eggs inside other insects- Larvae devours host from the inside killing it

Parasitoids

BLANK – array of species gradually shifts over time as organisms alter their own habitat

Ecological Succession

Occurs after a natural or human disturbance removes the natural array of species.

- Ex. Fire destroys a forest, abandoned plowed field, volcanic eruptions

Secondary Succession

species that can colonize a new habitat

overtime organic wastes & remains build up adding volume & nutrients

to allow tall trees to take hold

Pioneer species

What is the life span of annual plants?

1 year

(2 Seasons)

• Life Cycle: First year produces roots, stems, and leaves; second year produces flowers, seeds, and then dies.

Biennial Plants

BLANK (Multi-Season)

• Life Cycle: Live for more than two years, often returning for many years.

Perennial Plants

most common herbs are actually blank

perennial plants

Yes, both BLANK and BLANK are considered perennial plants, meaning they can live for several years with proper care

BLANK is the type of ecological succession in which organisms colonize an essentially lifeless area. It occurs in regions where the substrate lacks soil. Examples include areas where lava recently flowed, a glacier retreated, or a sand dune formed.

Primary Succession

BLANK (+ / -): The BLANM gains, the BLANK is harmed.

• Examples: Ticks/fleas on a dog, tapeworms in humans, mistletoe on trees.

BLANK (+ / 0): The BLANK gains, the BLANK is unaffected.

• Examples: Barnacles on a whale, remora fish on sharks, bird nests in trees.

• BLANK (+ / +): Both organisms benefit.

  • Examples: Bees and flowers, clownfish and anemones, gut bacteria in humans.
