Question

drag the labels from the left to the appropriate locations to complete this table about interspecific interactions.

• use labels of group 1 to identify the effect of the interaction on each species.
• use labels of group 2 to identify the type of interaction.

labels may be used once, more than once, or not at all.
(table content:
interaction between species 1 and species 2 | effect on species 1 | effect on species 2 | type of interaction
caterpillars (1) eat passionflower leaves (2). | a (g1) | b (g1) | c (g2)
weeds (1) grow among tomato plants (2). | - | d (g1) | e (g2)
honeybees (1) pollinate daisies (2) while feeding on their nectar and pollen. | f (g1) | g (g1) | mutualism
fleas (1) feed on the blood of cats (2). | h (g1) | i (g1) | j (g2)
unicellular algae (1) live inside cells of corals (2). | k (g1) | + | l (g2)
black rat snakes (1) eat rats (2). | m (g1) | - | n (g2)
house sparrows (1) house finches (2) require similar food and nest sites. | o (g1) | p (g1) | q (g2)
left labels: +, -, competition, herbivory, mutualism, parasitism, predation)

Explanation:

Step1: Define interaction effects/types

Group 1: $+$ = positive effect, $-$ = negative effect
Group 2: herbivory, competition, mutualism, parasitism, predation

Step2: Analyze caterpillar-plant interaction

Caterpillars gain food (+), plant loses tissue (-); interaction is herbivory.
Effect on 1: $+$, Effect on 2: $-$, Type: herbivory

Step3: Analyze weed-tomato interaction

Weeds compete for resources (+), tomato is outcompeted (-); interaction is competition.
Effect on 2: $-$, Type: competition

Step4: Analyze honeybee-daisy interaction

Mutualism means both benefit.
Effect on 1: $+$, Effect on 2: $+$

Step5: Analyze flea-cat interaction

Fleas gain nutrients (+), cat loses blood/harmed (-); interaction is parasitism.
Effect on 1: $+$, Effect on 2: $-$, Type: parasitism

Step6: Analyze algae-coral interaction

Coral benefits (+), so algae also benefits (+); interaction is mutualism.
Effect on 1: $+$, Type: mutualism

Step7: Analyze snake-rat interaction

Snake gains food (+), rat is killed (-); interaction is predation.
Effect on 1: $+$, Type: predation

Step8: Analyze sparrow-finch interaction

Both compete for shared resources, so both are harmed (-); interaction is competition.
Effect on 1: $-$, Effect on 2: $-$, Type: competition

Answer:

Interaction between species 1 and species 2	Effect on species 1	Effect on species 2	Type of interaction
Weeds (1) grow among tomato plants (2).	$-$	$-$	competition
Honeybees (1) pollinate daisies (2) while feeding on their nectar and pollen.	$+$	$+$	mutualism
Fleas (1) feed on the blood of cats (2).	$+$	$-$	parasitism
Unicellular algae (1) live inside cells of corals (2).	$+$	$+$	mutualism
Black rat snakes (1) eat rats (2).	$+$	$-$	predation
House sparrows (1) house finches (2) require similar food and nest sites.	$-$	$-$	competition
